Bhagavatapurana 9.6.50

50. Ah! Look at my fall, though I was a tapaswin of rigid vows, pious conduct, brought on by association with the acquatic creature under water! The light of Brahman which I had long enjoyed is lost.

51. He who seeks after release from Samsara ought by all means to avoid association with those that are given to family life and ought not to allow their senses to wander outside; he should be alone in seclusion and fix his mind on the unlimited Lord and betake himself only to the righteous who are devoted to Him, if at all there should be any association.
