Any service, be it in a hospital or in the Bhajan Group, have to be done with humility and reverence. Only then can they yield chiththa suddhi (purification of mind and thought), which is the main benefit derivable from Service. The constant recital of the Name of God - any of the million Names by which He is identified by human imagination or intelligence - is the best means of correcting and cleansing the mind of man...By means of the Name, you can keep God ever near you.

- Divine Discourse, December 21, 1967.

It is only when one engages in selfless service that love can be purified. - Baba
