Bhagavatapurana 11.2.52

52. He is indeed the highest votary of the Lord who is tranquil and equal to all beings and in whose view the distinction in respect of wealth or even the body does not exist as one's own or as belonging to another.

53. He is the foremost follower of Vishnu whose memory of the Lord is not interrupted even for the sake of the wealth of the three worlds and who does not get away from (forget), even for half a minute or half a second, the lotus-like feet of the Lord which are sought after by the gods and others that have not conquered their mind.
