Lochan Das Thakur has written this song “Vrajendra Nandana Bhaje Jei Jana”. In this song, Lochan Das Thakur describes the significance of the one who worships Lord Krsna.
vrajendra-nandana, bhaje jei jana, saphala jivana ta’ra,
tahara upama, vede nahi sima, tri-bhuvane nahi ara
emana madhava, na bhaje manava, kakhana mariya jabe,
sei se adhama, prahariya yama, raurave krmite khabe
ta’ra-para ara, papi nahi chara, samsara jagat-majhe,
kona kale ta’ra, gati nahi ara, michai bhramiche kaje
sri locana dasa, bhakatira asa, hari-guna kahi likhi,
hena rasa-sara, mati nahi ja’ra, ta’ra mukha nahi dekhi
1) That person who worships Vrajendra-nandana makes his life successful. In the three worlds there is none equal to Him. The Vedas cannot completely describe His glories.
2) Whoever fails to worship that Sri Madhava is taken to Yamaraja after death and put in the hell called Raurava-loka (where he is eaten alive by worms and insects). There is no one as sinful as him.
3) Since there is no greater sinner than he throughout the universe, he cannot be delivered at any time but continues to wander, performing temporary materialistic activities that result in suffering.
4) Sri Locana dasa states, "Only by my desire to obtain bhakti am I able to describe Sri Hari’s qualities. I never wish to see the face of that person whose intelligence is not fixed on Vrajendra-nandana, the very essence and embodiment of all rasa.
