Śrīmad-Bhāgavatam · Text 11.9.22
Who is speaking and story frame
यत्र यत्र मनो देही धारयेत् सकलं धिया ।
स्नेहाद् द्वेषाद् भयाद् वापि याति तत्तत्स्वरूपताम् ॥ २२ ॥
yatra yatra mano dehī
dhārayet sakalaṁ dhiyā
snehād dveṣād bhayād vāpi
yāti tat-tat-svarūpatām
If out of love, hate or fear an embodied soul fixes his mind with intelligence and complete concentration upon a particular bodily form, he will certainly attain the form that he is meditating upon.
