By moderating and modulating habits of eating and drinking, one can lay the foundation for spiritual life. By drinking intoxicating stuff, one loses control over the emotions and passions, the impulses and instincts, the speech and movements, and one even descends to the level of beasts. By eating flesh, one develops violent tendencies and animal diseases. The mind becomes more intractable when one indulges in rajasic food; it can never be remoulded if tamasic food is consumed with relish. To dwell in Rama thatwa (Rama Principle) constantly, one has to be vigilant about food and drink consumed by both body and mind.
