udasinas ca dehadav
atmarama dhrta-vratah
mayy avesya manah samyan
mam ante brahma yasyatha
Translation:
Be detached from the body and everything connected to it. Remaining self-satisfied, steadfastly keep your vows while concentrating your minds fully on Me. In this way you will ultimately attain Me, the Supreme Absolute Truth.
