Health does not depend on medicine -- good words, good manners, good sight, good thoughts—these are essential. What can even powerful or costly medicines do if one is ill with bad thoughts and bad feelings? On the other hand, virtuous living, beneficial thoughts, elevating ideals, and righteous conduct can confer not only health but what is even more precious, Atmananda, the Ecstatic Awareness of the Reality itself.

Life at Prasanthi Nilayam must deepen faith in the seva path to salvation. It is the attitude that is important. The particular item of service might be small. You may not get a chance to partake in some gigantic scheme of service through which millions may be benefitted; you can lift a lame lamb over a stile, or lead a blind child across a busy road. That too is an act of worship.
