What Are the Four Iddhipada? Chanda, Viriya, Citta, Vimamsa

The four iddhipada are four qualities that lead to success: chanda, viriya, citta and vimamsa, with the Navakovada's wording, the Pali with a translation, and everyday examples

The four iddhipada are four qualities that form the base of, or the way to, success: chanda, delight in what you do; viriya, effort; citta, close attention that does not drop the task; and vimamsa, checking and reflecting with reasons. This teaching applies to study, work and meditation alike. The Buddha spoke about the iddhipada in a great many discourses, gathered in the Iddhipāda Saṁyutta, chapter 51 of the Saṁyutta Nikāya. This page explains what the four iddhipada mean and what each one means, quotes the Navakovada's wording in full, gives the Pali with a translation from the Vibhaṅga Sutta (SN 51.20), everyday examples, what to do when one of them is weak, and a summary at the end.

What are the four iddhipada? The meaning of the word

The word iddhipada comes from the Pali iddhipāda, made of iddhi, meaning success, accomplishment or power, and pāda, meaning a foot, a base, or the way that leads somewhere. So iddhipada can be translated as 'base of success' or 'way to success'. The Navakovada defines it briefly as 'qualities that bring about what one intends': qualities of mind that make what we set out to do actually succeed, instead of staying an intention.

In the discourses the four iddhipada are not just a method for getting work done. They are part of the thirty-seven bodhipakkhiyadhamma, the qualities on the side of awakening: the four foundations of mindfulness, the four right efforts, the four iddhipada, the five faculties, the five powers, the seven awakening factors and the noble eightfold path. The Navakovada lists these too, in its Dhamma-lists section. So the highest success the iddhipada lead to is freedom from the defilements, while success in study and work is the same principle applied to everyday matters. Both rely on the same mechanism: a mind that wants to do something, does it, stays with it, and reflects and corrects until the work is done.

What the four iddhipada are: the Navakovada's wording

The Navakovada, a widely used first-level Dhamma textbook, places the iddhipada in its Dhamma-lists section, in the chapter of fours. What follows is the Navakovada's own wording (our translation), under the heading 'Iddhipada: the qualities that bring about what one intends, four in number'.

1. Chanda: delight in and love for the thing.
2. Viriya: persevering in doing the thing.
3. Citta: giving one's mind to the thing and not putting the task down.
4. Vimamsa: diligently reflecting on and examining the reasons in the thing.

The Navakovada closes the list with: 'When these four qualities are complete, they can lead a person to what they want, provided it is not beyond their range', and gives its source as the Vibhaṅga of the Abhidhamma Piṭaka. 'Not beyond their range' means not beyond that person's ability. So the sentence says plainly that the four iddhipada do not make the impossible possible; they make what is within our reach actually succeed, instead of stalling halfway.

Chanda, viriya, citta, vimamsa: one by one

1. Chanda: liking, the wish to do. Here it is not greedy wanting but a heart that sees the value of the work and wants to do it well. Chanda lets you start without anyone forcing you, and keeps effort from turning into a grudging struggle. Someone without chanda works because they have to, does the minimum, and stops at the first excuse.
2. Viriya: effort, the courage to act, and not losing heart at obstacles. It does not mean overdoing things; it means coming back to the work steadily. In the discourses every one of the iddhipada carries the words padhānasaṅkhāra, 'active effort', which shows that effort is indispensable whichever quality leads.
3. Citta: a mind devoted and attentive that does not put the task down; a mind that stays with the work even when you are not actively doing it, keeps it in mind, cares about it, and does not let it slip out of attention. Citta differs from viriya in that viriya is the force of doing, while citta is commitment and continuity of attention. Learners often find this one confusing, because citta literally means 'mind'; in the iddhipada it means a mind settled on what it is doing.
4. Vimamsa (vīmaṁsā): reflecting, checking and looking for reasons: is what I am doing working, why, and what needs fixing? Vimamsa keeps effort from being wasted, because someone who works hard without reflecting can repeat the wrong method for a long time without noticing. It is the one of the four iddhipada that uses wisdom most.

The four work together, but in each person one of them usually stands out and leads. Some start from love of the work, some from hard work, some from a commitment that will not let go, and some from curiosity about how to do it better. That is why the discourses explain them as four: each is concentration led by that quality, with the others following to help. Once you know which one is strongest in you, use it as your starting point, then build up the ones that are weaker.

The Pali with a translation from the Vibhaṅga Sutta (SN 51.20)

The Vibhaṅga Sutta is one of the most detailed explanations of the iddhipada. It opens with these words:

Cattārome, bhikkhave, iddhipādā bhāvitā bahulīkatā
mahapphalā honti mahānisaṁsā.

Mendicants, these four bases of power, when developed and cultivated, are very fruitful and very beneficial.

SN 51.20

Then he explains the first of them:

Idha, bhikkhave, bhikkhu chandasamādhippadhānasaṅkhārasamannāgataṁ iddhipādaṁ bhāveti:
iti me chando na ca atilīno bhavissati, na ca atippaggahito bhavissati,
na ca ajjhattaṁ saṅkhitto bhavissati, na ca bahiddhā vikkhitto bhavissati.

Mendicants, here a mendicant develops the base of power that has concentration due to enthusiasm and active effort, thinking: 'My enthusiasm will be neither too slack nor too tense, neither shrunk inward nor scattered outward.'

SN 51.20

The discourse then explains each term. Too slack means mixed with laziness; too tense means mixed with restlessness; shrunk inward means mixed with dullness and drowsiness; scattered outward means the mind runs after the five kinds of attractive sights, sounds, smells, tastes and touches. These four resemble the five hindrances, which keep the mind from settling. Note that the discourse does not teach having as much enthusiasm or effort as possible, but having the right amount, and it applies the same principle to energy, mind and inquiry.

The discourse also has the iddhipada developed evenly, in the words 'as before, so after; as below, so above; as by day, so by night', and explains that 'as by day, so by night' means developing them with the same features, qualities and signs by day and by night. The point is consistency, not good intentions only at certain times. The discourse goes on to say that a mendicant who develops the iddhipada like this can wield many kinds of power, which is the original sense of iddhi in the discourses. But the last result it names, the goal of the practice, is this:

Evaṁ bhāvitesu kho, bhikkhave, bhikkhu catūsu iddhipādesu evaṁ bahulīkatesu,
āsavānaṁ khayā anāsavaṁ cetovimuttiṁ paññāvimuttiṁ
diṭṭheva dhamme sayaṁ abhiññā sacchikatvā upasampajja viharati.

Mendicants, when a mendicant has developed and cultivated the four bases of power in this way, they realise with their own insight, in this very life, the freedom of heart and freedom by wisdom that are without defilements, through the ending of the defilements, and they live having attained it.

SN 51.20

The four iddhipada in daily life: examples

The four iddhipada work for any task that has to be kept up over time. These examples show what each one looks like in real situations.

• A student preparing for an exam: chanda is seeing what is useful or interesting in the subject, not reading only out of fear of failing. Viriya is reading an hour every day instead of cramming the night before. Citta is switching the phone off while reading and going over the material in your head during the day. Vimamsa is trying past papers, seeing where you go wrong, and going back to read those parts again.
• Someone at work: chanda is understanding whom your work helps and why it matters. Viriya is doing the hard part first instead of putting it off. Citta is following the job through to the end and not leaving it hanging. Vimamsa is reviewing afterwards what worked and what you will do differently next time.
• Building a new habit, such as starting to exercise: chanda is choosing an activity you really enjoy. Viriya is sticking to the schedule even on days you don't feel like it. Citta is keeping a log and holding the goal in mind. Vimamsa is noticing how your body responds and adjusting the load to suit.
• Meditation: chanda is wanting to practise because you see the value of a calm mind. Viriya is staying seated even when the mind is not yet calm. Citta is coming back to the breath every time the mind slips away. Vimamsa is noticing whether the mind is drowsy or restless and adjusting to fit. Beginners can read more on how to sit for meditation.

When one of them is weak, what to do

When work is not moving forward, ask which of the four is missing and work on that one, instead of blaming yourself in general for not being good enough.

• Weak chanda, feeling bored and not wanting to start: go back to why you are doing it, write the reason down in a line, or break the work into pieces small enough to see progress. Liking often follows progress you can see.
• Weak viriya, putting things off: set a fixed time, start with the smallest piece you can do right now, and count consistency rather than quantity.
• Weak citta, forgetting or dropping the task after a short while: do one thing at a time, put distractions out of reach, and go over your goal briefly every morning.
• Weak vimamsa, working hard without progress: stop and look honestly at the results, ask someone who knows more, and change one thing at a time to see what works.
• Too tense, stressed and anxious: ease off, rest enough, and remember that the discourse teaches balance, not overdoing it. If you are drowsy, get up and change posture; if the mind drifts to pleasures, bring it back to the task.

How the four iddhipada differ from the four sangahavatthu

These two lists are often learned together, but they serve different purposes. The four iddhipada are for getting your own work done; they look inward, at whether you want to do it, work at it, pay attention and reflect. The four sangahavatthu, giving, kind words, helpful conduct and equal treatment, are for holding other people together; they look outward, at relationships. Most real work needs both. A student group project, for example, succeeds when each member brings the iddhipada to their own part and the group looks after one another with the sangahavatthu.

The four iddhipada in English

In English books the four iddhipada are usually called the four bases of power, the four bases of success, or the four roads to power. Common English renderings of each are:

• Chanda: desire to act, zeal, enthusiasm
• Viriya: energy, effort, persistence
• Citta: mind, intentness, dedication
• Vimamsa: investigation, inquiry, review

The four iddhipada in brief

• The four iddhipada are four qualities that are the base of success: chanda, viriya, citta, vimamsa.
• Chanda: love what you do. Viriya: work at it. Citta: keep it in mind and don't drop it. Vimamsa: reflect and correct.
• All four need balance: not slack, not tense, not shrunk inward, not scattered outward.
• They serve study, work and meditation, and are part of the thirty-seven qualities on the side of awakening.
• The iddhipada make what is within reach actually succeed; they do not make what is beyond reach possible.
