Answer
Yes—but that stage is attained only after returning to the spiritual world.
As long as we inhabit a material body, we must properly nourish the body, mind, and senses. The acharyas have taught us how to maintain them in a way that supports spiritual advancement.
The goal is to attain our eternal spiritual body (sat-cit-ananda body), which does not require material fuel such as food and sleep.
Our present body is temporary and is merely a vehicle. The soul's real nourishment is sat-cit-ananda, but because of ignorance we identify with the body and live in illusion.
Material happiness is temporary and always mixed with suffering. Real spiritual practice gradually awakens our true identity as eternal spirit, not matter.
