Back to classic theosophy quotes

He who hears his brother reviled,
and keeping a smooth face leaves the abuse unnoticed, tacitly agrees with the enemy,
as if he admitted the same to be proper and just.
He who does it is either mouse-hearted, or selfishness is at the bottom of his heart.
He is not fit as yet to become a 'companion'.
