“ ‘One who is equal to friends and enemies, who is equipoised in honor and dishonor, heat and cold, happiness and distress, fame and infamy, who is always free from attachment to material things and always grave and satisfied in all circumstances, who doesn’t care for any residence, and who is always fixed in devotional service — such a person is very dear to Me.
