Humbleness is the sign of progress in Krishna Consciousness.
A Krishna Consciousness person thinks always about himself as the lowest creature in the world,
and the more one thinks like that he becomes elevated more and more.
A Krishna Conscious person is never falsely puffed-up;
he is satisfied with his humble position
as the servant of the servant of the servant of Krishna.
Srila Prabhupada letter to: Krishna dasa, June 1, 1968
