गोविन्द भाष्य (श्रील बलदेव विद्याभूषण - अचिन्त्यभेदाभेद वेदान्त ब्रह्मसूत्र भाष्य सटीक)

iyad āmananāt
iyat—this; āmananāt—by the description.
It follows the description.
Purport by Śrīla Baladeva Vidyābhūṣaṇa
The word "iyat" means "in that way". In that way one should always meditate
on the qualities of the Supreme Lord's transcendental form. In what way? The
sūtra explains: "āmananāt" (following the description). This means, "following the
description of the Lord's primary qualities". On the Lord's primary qualities are
compulsory in meditation on Him. Therefore it is not necessary that in every
meditation on the Lord one must meditate on His doing everything or possessing
all fragrances.

yaḥ sarva-jñaḥ sarva-vid yasyaiṣa mahimā bhuvi sambabhūva divye pure hy eṣa
samvyomny ātmā pratiṣṭhitaḥ.
"The all-knowing Supreme Personality of Godhead, whose greatness is seen
everywhere in the world, resides in His own effulgent city in the spiritual sky."
However, it is also said (Muṇḍaka Upaniṣad 2.2.10):
brahmaivedam viśvam idaṁ variṣṭham
