Katha-1-2-11-kāmasyāptiṃ

Sri Shankara’s Commentary (Bhashya) translated by S. Sitarama Sastri

But you having beheld the end of all desires (for, here, i.e., in Hiranyagarbha, all desires are fulfilled), the support of all the worlds comprising the Adhyâtma, the Adhibhûta and the Adhidaiva, i.e., (the bodies, elements and gods), the immortal goal of worship, the place of Hiranyagarbha, the extreme state of fearlessness, praiseworthy, great as combining many desirable powers such as animâ (praiseworthy and great because it is unsurpassable) the boundless and unsurpassable goal of the âtman, have boldly, being intelligent, rejected, wishing only for the highest, all this host of enjoyments within the pale of Samsâra. Oh, what unsurpassable qualities you possess!
