Service keeps you quite fit and healthy. Service gives you immeasurable joy. Service prepares you to take up Vedanta. Service enables you to worship God truly. Service generates the Advaita Bhava or unity. Service induces compassion and mercy. Service gives longevity. Vedanta without service is a husk. Bhakti without service is barren. Therefore, serve all with Atma Bhav. All knowledge is vain if you do not serve with love and affection. All service is empty if there is no love, affection and sincerity. If you serve with love, selflessly, God is behind you; The strength of the whole world is behind you. Therefore serve with love, sincerity and devotion. Selfless service is love made visible.
