In plain words
This is called “avataraṇa”, coming down. Coming down does not mean coming from above to below. Its meaning is coming to the level of those whom one is to bless. If you tell a little baby down below to jump up onto your hip, it cannot come. “Am I not a grown man? I cannot bend,” you say, and the child will not come into your hands. Merely bending does not mean giving in! In the same way, not as stooping to the child, one must come down to his level in order to teach him. This is the chief principle of Prema.
