Krishna explains that yoga requires moderation in lifestyle. 'Nātyaśnatas tu yogo 'sti'—there is no yoga (yogaḥ) for one who eats too much (atyśnataḥ). This means: overeating makes you sluggish, heavy, unable to meditate. 'Na caikāntam anaśnataḥ'—and (ca) not (na) for one who does not eat (anaśnataḥ) exclusively (ekāntam). This means: not eating at all, or eating too little, makes you weak, unable to sustain practice. 'Na cāti-svapna-śīlasya'—and (ca) not (na) for one who sleeps too much (ati-svapna-śīlasya). This means: excessive sleep makes you lazy, dull, unable to be alert. 'Jāgrato naiva cārjuna'—and (ca) not (na) for one who does not sleep (jāgrataḥ), O Arjuna (arjuna). This means: not sleeping enough makes you exhausted, unable to focus. Yoga requires balance—moderate eating, moderate sleep. Neither extreme works—too much or too little of either prevents yoga.
How this ancient wisdom applies to your daily life

Yoga requires moderation in lifestyle. You can't become a yogi if you eat too much—overeating makes you sluggish, heavy, unable to meditate. You can't become a yogi if you eat too little—undereating makes you weak, unable to sustain practice. You can't become a yogi if you sleep too much—excessive sleep makes you lazy, dull, unable to be alert. You can't become a yogi if you don't sleep enough—insufficient sleep makes you exhausted, unable to focus. Yoga requires balance—moderate eating, moderate sleep. Neither extreme works. Too much or too little of either prevents yoga. This applies to all aspects of life—not just eating and sleeping, but everything. Moderation is the key to yoga.

Are you eating and sleeping in moderation, or are you at one extreme or the other? Is your lifestyle balanced, or is it preventing you from practicing yoga?
