“Adhyathmic [individual personal] sorrow is caused by the human body, the home of countless microbes, and other parasitic beings. No one can be free from these disease-inducing causes. But, one can easily overcome this sorrow by developing feelings of compassion towards all beings and thoughts which thrive on Love and spread love. Illness, both physical and mental, is a reaction on the body caused by poisons in the mind. An uncontaminated mind alone can ensure continuous health. Vice breeds disease. Bad thoughts and habits, bad company and bad food are fertile grounds where disease thrives. Arogya (good health) and Ananda (bliss) go hand in hand.”

“In rendering service, see that you do it for the satisfaction of your conscience and not to impress others. Treating service as an offering to the Divine, do it perfectly. Remember that God is watching every one of your actions. Be your own watchman to scrutinize what you do. When you do everything to satisfy your conscience, you are well on the way to Self-Realisation.”
