Premanand Maharaj Ji
Does eating less and eating light food help remove sleepiness and laziness?
Eat light and less to cut laziness
Sleep, laziness and pramad (carelessness) are born of tamogun. Eat sattvic food, and eat little; if you stuff yourself, tamogun will arise anyway.
Take sattvic food, and take it in small quantity. If you eat until you are stuffed, tamogun will certainly arise.
