yas citta-vijaye yattah
syan nihsango ’parigrahah
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
One who desires to conquer the mind must leave the company of his family and live in a solitary place, free from contaminated association. To maintain the body and soul together, he should beg as much as he needs for the bare necessities of life.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
This is the process for conquering the agitation of the mind. One is recommended to take leave of his family and live alone, maintaining body and soul together by begging alms and eating only as much as needed to keep himself alive. Without such a process, one cannot conquer lusty desires. Sannyasa means accepting a life of begging, which makes one automatically very humble and meek and free from lusty desires. In this regard, the following verse appears in the Smrti literature:
laksayitva grhi spastam
In this world of duality, family life is the cause that spoils one’s spiritual life or meditation. Specifically understanding this fact, one should accept the order of sannyasa without hesitation.
