SB 10.45.32
yathopasadya tau dantau
gurau vrttim aninditam
grahayantav upetau sma
bhaktya devam ivadrtau
Translation:
Sandipani thought very highly of these two self-controlled disciples, whom he had obtained so fortuitously. By serving him as devotedly as one would serve the Supreme Lord Himself, They showed others an irreproachable example of how to worship the spiritual master.
