The middle measure in food and sleep is the body's doorway into yoga.
The seeker imagines the inner path leaves the body behind, yet too much or too little of either food or rest unfits the very instrument meditation works through. Krishna names both extremes so the middle stands clear.
Yoga is not for one who eats too much, nor for one who does not eat at all. It is not for one who sleeps too much, nor for one who stays awake too long, Arjuna.
Having described the seat and posture of meditation, Krishna now turns to the outer regulation that prepares for it, ruling out both excess and deficiency before he turns inward to show how yoga actually comes about.
Where they agreethe convergence
Across schools and centuries the commentators come to the same ground. These are the points they share, and the voices that hold each one.
There is no yoga for one who eats too much, and none for one who eats nothing at all; either way the body turns from a support into an obstacle.

Krishna sets a rule of moderation as the doorway to yoga: there is no yoga for one who eats too much, and none for one who does not eat at all. 'Yoga' here is the disciplined practice of meditation that the chapter has been describing. The verse is stated negatively, ruling out both extremes, so that the middle path stands out by contrast. Eating beyond one's proper measure, often out of greed, harms the body and brings on disease such as indigestion; eating nothing, or far too little, starves the body of nourishment and makes it unfit for the work of practice. Either way the body becomes an obstacle rather than a support.
The same balance holds for rest: too much sleep makes you heavy and forgetful, too little leaves you nodding off, so keep the middle in this pair as in every other.

The same rule of moderation applies to sleep and waking: there is no yoga for one given to too much sleep, nor for one who keeps awake too much. Too much sleep makes the body heavy and the mind dull and forgetful, so meditation becomes impossible; too little sleep leaves one drowsy, so that one nods off during meditation itself. Several commentators extend the same balance to recreation, exertion, and movement, treating the verse as naming a few sample pairs rather than an exhaustive list. The single principle running through every pair is the same: avoid both the excess and the deficiency, and hold the middle.
Scripture gives a plain gauge here: fill half the stomach with food, a third with water, and leave a fourth empty for the breath, keeping the body strong enough to sit long.

Many commentators ground the food-rule in scripture and give a concrete measure. They cite the Shatapatha teaching that food taken in proper proportion protects the eater and does no harm, while food in excess harms and food too scanty fails to protect. As a practical gauge several quote the yoga texts: fill half the stomach with food, a third with water, and leave the remaining fourth empty for the free movement of air (the breath). The aim is a body kept healthy and strong enough to sit long in meditation, neither overfed into drowsiness nor starved into weakness.
Understand that this regulating of food and sleep is not yoga itself but its preparation, clearing away the drowsiness and restlessness that would pull the mind off its object.

The verse is read as practical preparation for yoga rather than yoga itself. Moderating food and sleep is an aid or apparatus that makes the body and mind ready, removing the disturbances of drowsiness and restlessness that would otherwise pull the mind off its object. The direct address to Arjuna is taken as a personal nudge to be watchful and to give up any excess, since otherwise the practice itself collapses. Having closed off the outer regulation of the body in this verse, Krishna will turn inward in what follows to describe how yoga actually comes about.
This is the shared ground; it can be carried as it is. Below is where they differ.
Where they differthe divergence
Dvaita, in their fuller words
These commentators read the verse as a conditional prohibition rather than an absolute one. The ban on going without food and on keeping watch applies specifically to the person who is unable to bear such austerity; it is not a blanket prohibition for everyone. They cite the Naradiya, which says that the one who is able may put away sleep, eating, fear, and restless movement and, meditating with eyes slightly closed, become serene. So fasting and wakefulness are forbidden only to the unfit; for the capable practitioner they remain permitted. On this reading the verse states a purpose, guarding the weak, rather than condemning austerity as such.
Śuddhādvaita, in their fuller words
These commentators read the body as the vehicle of devotional service. One source frames abstaining from food as defective when it is undertaken merely as a fast 'without knowing the very form of Bhagavan,' and treats yoga here as union with the Lord himself; the body is to be neither indulged into thickness nor starved into weakness but held as 'the chariot of seva,' the service of God. The other source stresses that for the one of measured food and motion, yoga becomes the very remover of sorrow. Moderation is thus placed in service of loving union, not mere fitness.
A few questions to carry
These ask for understanding, not recall; each answer is settled by the commentary itself.
For a second sitting
Carry this with youwhat stays
Keep the golden medium in eating and in sleeping. Eat neither more nor less than what your body actually needs to stay healthy and strong. If you eat too much you grow drowsy and sleep overpowers you, and indigestion follows; if you eat too little you grow weak and cannot sit long for meditation. The same holds for rest: too much sleep leaves the mind dull and the body heavy, and too little leaves you nodding off in meditation itself. Watch the middle in both, and your progress in yoga will be rapid.
Watch the middle today in what you eat and how you rest, taking neither more nor less than your body truly needs, and let it become a quiet support rather than a hindrance to your practice.

A Seeker Asks
Why would a spiritual path that aims beyond the body insist so plainly on regulating something as ordinary as how much I eat and sleep?
Because the body is the instrument through which meditation happens, and an instrument out of balance cannot do the work. Eating too much brings drowsiness, heaviness, and disease, so the mind cannot settle; eating too little leaves the body too weak to sit and hold attention. The same logic governs sleep: oversleeping dulls the mind into forgetfulness, while too little leaves you drowsy and nodding off in meditation. Regulating food and sleep is not the goal but the preparation that removes these disturbances.
Śaṅkarācārya · Madhusūdana Sarasvatī · Swami Sivananda · Swami Ramsukhdas · Vedānta Deśika
The point is not austerity for its own sake but the middle path. The verse rules out both extremes precisely so the seeker holds the balance: neither overfed nor fasting, neither oversleeping nor forcing wakefulness. Scripture gives a concrete gauge, that food in proper proportion protects while excess harms and too little fails to nourish, with the practical measure of filling half the stomach with food, a third with water, and leaving a fourth for the breath. When the body is held in this balance it stops being a hindrance and becomes a steady support.

Contemplation
Keep the golden medium in eating and in sleeping. Eat neither more nor less than what your body actually needs to stay healthy and strong. If you eat too much you grow drowsy and sleep overpowers you, and indigestion follows; if you eat too little you grow weak and cannot sit long for meditation. The same holds for rest: too much sleep leaves the mind dull and the body heavy, and too little leaves you nodding off in meditation itself. Watch the middle in both, and your progress in yoga will be rapid.
