“Keeping the mind fixed on God and good ideas and things also helps health. Keep the eye, ear, tongue, hands and feet under restraint. Don't read enervating or exciting stuff; don't attend film shows which exhaust or inflame the mind. Don't lose faith in yourself, you are the Divine encased in the body. Contentment is the best tonic; why inflict on yourself the disease of greed and consume tonics to get strength, and to hanker further? Use the body as a boat to cross the ocean of life, with devotion and detachment as the two oars.”

“When we do service, instead of merely doing service for one's own satisfaction, service that is done keeping the satisfaction of the recipient in the mind is the best form of seva. You must first introspect if your act of service is causing any harm or inconvenience to others. …Serving humans alone is not service. It is essential to serve all beings and creatures when the need arises. God is present in all beings. You must first recognise this Truth that God is present in all. It is only when this sacred thought is established in your mind, the seva that you do is sanctified. Without this faith and belief, any service rendered merely for earning name and fame will not aid you in sanctifying your life.”
