11.15.22

यदा मन उपादाय यद् यद् रूपं बुभूषति । तत्तद् भवेन्मनोरूपं मद्योगबलमाश्रय: ॥ २२ ॥

yadā mana upādāya yad yad rūpaṁ bubhūṣati tat tad bhaven mano-rūpaṁ mad-yoga-balam āśrayaḥ

yadā
when
manaḥ
the mind
upādāya
applying
yat yat
whatever
rūpam
form
bubhūṣati
one desires to assume
tat tat
that very form
bhavet
may appear
manaḥ-rūpam
the form desired by the mind
mat-yoga-balam
My inconceivable mystic potency, by which I manifest innumerable forms
āśrayaḥ
being the shelter

When the yogī, applying his mind in a certain way, desires to assume a particular form, that very form immediately appears. Such perfection is possible by absorbing the mind in the shelter of My inconceivable mystic potency, by which I assume innumerable forms.
