11.18.9

एवं चीर्णेन तपसा मुनिर्धमनिसन्तत: । मां तपोमयमाराध्य ऋषिलोकादुपैति माम् ॥ ९ ॥

evaṁ cīrṇena tapasā munir dhamani-santataḥ māṁ tapo-mayam ārādhya ṛṣi-lokād upaiti mām

evam
thus
cīrṇena
by the practice
tapasā
of austerity
muniḥ
the saintly vānaprastha
dhamani-santataḥ
emaciated so much that the veins are visible throughout his body
mām
Me
tapaḥ-mayam
the goal of all penance
ārādhya
worshiping
rṣi-lokāt
beyond Maharloka
upaiti
achieves
mām
Me

The saintly vānaprastha, practicing severe penances and accepting only the bare necessities of life, becomes so emaciated that he appears to be mere skin and bones. Thus worshiping Me through severe penances, he goes to the Maharloka planet and then directly achieves Me.
