True service springs out of selfless love and it must scatter love in profusion.

People say that service to humanity (manava seva) is service to God (Madhava seva). That is true. But although the service of humanity is holy, unless it is merged in the bigger ideal, people won't benefit, however huge the service. Mere repetition of the slogan is useless if service is done without faith in the divinity of people and with an eye on name and fame and the fruits of one's action. Whatever actions one undertakes, if one constantly has as companion the contemplation of the Lord, and faith in the essential divinity of people, then the statement about service to humanity and service to God being the same is justified. Without thoughts of God (Madhava), how can service to God originate? Instead, whatever is done with the Lord in mind, along the path of truth and according to aspects of dharma, has to be considered as selfless service (seva) to the Lord.
