"Since mental tension is most detrimental to man's health, man should learn the art of controlling his passions and emotions, which cause stresses and strains. It is also essential to keep our mind serene and peaceful while eating food. We should not indulge in discussion of topics which will cause agitation and excitement and disturb our mental peace while we are taking food. Mental tension is responsible for ill health. We should also avoid viewing TV, video etc, while eating food, as they may cause mental disturbances." 
…Sathya Sai Baba, “Food, the heart and the mind” Discourse January 21, 1994

"You should not be ever entangled in the meshes of this world and its problems. Try to escape into the purer air of the spirit as often as you can, taking the name of the Lord on your tongue. Of the 24 hours of the day, have 6 hours for your individual needs, 6 hours for the service of others, 6 hours for sleep and 6 for dwelling in the Presence of the Lord. Those six hours will endow you with the strength of steel."
