11.17.38

गृहं वनं वोपविशेत् प्रव्रजेद् वा द्विजोत्तम: । आश्रमादाश्रमं गच्छेन्नान्यथामत्परश्चरेत् ॥ ३८ ॥

gṛhaṁ vanaṁ vopaviśet pravrajed vā dvijottamaḥ āśramād āśramaṁ gacchen nānyathāmat-paraś caret

gṛham
the family home
vanam
the forest
vā
either
upaviśet
one should enter
pravrajet
one should renounce
vā
or
dvija-uttamaḥ
a brāhmaṇa
āśramāt
from one authorized status of life
āśramam
to another authorized status
gacchet
one should go
na
not
anyathā
otherwise
amat-paraḥ
one who is not surrendered to Me
caret
should act

A brahmacārī desiring to fulfill his material desires should live at home with his family, and a householder who is eager to purify his consciousness should enter the forest, whereas a purified brāhmaṇa should accept the renounced order of life. One who is not surrendered to Me should move progressively from one āśrama to another, never acting otherwise.
