Your body is your first home. If it burns down, you have nowhere to live. Every lesson here is maintenance — the boring, daily, inglorious work of keeping yourself alive.
The body is the vessel through which all other knowledge flows. Without health, every other discipline is theoretical. Kaya-Vidya is not merely physical education — it is the science of inhabiting yourself with awareness, discipline, and care.
Discipline is not willpower — it is muscle. The student who does ten push-ups daily learns that consistency defeats intensity. A 30-minute walk can save you from a 3-hour spiral. This is trivially physical. It is also the entire secret to life.
