A devotee does not attach much importance to the pains and trouble pertaining to the body because he knows perfectly well that he is not the material body. He does not identify with the body; therefore he is freed from the conception of false ego and is equipoised in happiness and distress. He is tolerant, and he is satisfied with whatever comes by the grace of the Supreme Lord. BG 12.13-14, Purport
Without being fearless, one cannot be joyful. The bhaktas, the devotees, are fearless and always joyful because they are constantly engaged in the service of the lotus feet of the Lord. SB 4.24.52
Fill your consciousness with service towards the Lord and keep always within your heart the Divine Darshan of Sri Radha Shyamsunder, Sri Krishna Balaram and Sri Gaura Nitai and dive in the bliss of being Krishna Conscious. Jai Srila Prabhupada!
