Srimad Bhagavatam Canto 01, Chapter 13, Text 26

SB 1.13.26

gata-svartham imam deham
virakto mukta-bandhanah
avijñata-gatir jahyat
sa vai dhira udahrtah
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
He is called undisturbed who goes to an unknown, remote place and, freed from all obligations, quits his material body when it has become useless.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
Narottama dasa Thakura, a great devotee and acarya of the Gaudiya Vaisnava sect, has sung, “My Lord, I have simply wasted my life. Having obtained the human body, I have neglected to worship Your Lordship, and therefore I have willingly drunk poison.” In other words, the human body is especially meant for cultivating knowledge of devotional service to the Lord, without which life becomes full of anxieties and miserable conditions. Therefore, one who has spoiled his life without such cultural activities is advised to leave home without knowledge of friends and relatives and, being thus freed from all obligations of family, society, country, etc., give up the body at some unknown destination so that others may not know where and how he has met his death. Dhira means one who is not disturbed, even when there is sufficient provocation. One cannot give up a comfortable family life due to his affectionate relation with wife and children. Self-realization is obstructed by such undue affection for family, and if anyone is at all able to forget such a relation, he is called undisturbed, or dhira. This is, however, the path of renunciation based on a frustrated life, but stabilization of such renunciation is possible only by association with bona fide saints and self-realized souls by which one can be engaged in the loving devotional service of the Lord. Sincere surrender unto the lotus feet of the Lord is possible by awakening the transcendental sense of service. This is made possible by association with pure devotees of the Lord. Dhrtarastra was lucky enough to have a brother whose very association was a source of liberation for this frustrated life.
