The Lord likes to be called Aartha-thraana-paraayana (protection of, and devoted to, the distressed and oppressed) more than any other name, for He is most happy when He rescues those in agony. See how He yielded to the entreaties of Sugriva who required Him to demonstrate His prowess before surrendering to Him! He wanted to rescue Sugriva, who had lost his kingdom and his queen, and so He was willing to be put to test by that apprehensive supplicant! (SSS Vol. 6, pp. 128-129)
