" ... fellowship with the righteous cleanseth the rust from off the heart."

"O MY SON! The company of the ungodly increaseth sorrow, whilst fellowship with the righteous cleanseth the rust from off the heart. He that seeketh to commune with God, let him betake himself to the companionship of His loved ones; and he that desireth to hearken unto the word of God, let him give ear to the words of His chosen ones."

-Bahá'u'lláh, The Hidden Words of Bahá’u’lláh, Persian No. 56, p. 42
