स पर्यगात् शुक्रमकायमव्रणम् अस्नाविरं शुद्धमपापविद्धम्। कविर्मनीषी परिभूः स्वयम्भूः याथातथ्यतोऽर्थान् व्यदधात् शाश्वतीभ्यः समाभ्यः ॥८॥
sa paryagāt śukramakāyamavraṇam asnāviraṁ śuddhamapāpaviddham। kavirmanīṣī paribhūḥ svayambhūḥ yāthātathyato'rthān vyadadhāt śāśvatībhyaḥ samābhyaḥ ॥8॥
He is the all pervading, without misery, undecaying, without gross body, pure, untouched by sin, omniscient, wise, omnipresent, self-existent. He manifests eternally existing reality, as it is, impartially.
Īśā.Bhāshya 08
A reference is provided to the portion of Varaha Purāna which explains every word in the current verse.
It is called 'śukra' (spotless) as it is without the wound of sorrow, is 'avraṇa' (without wound) as it is always complete, is 'śuddha' (pure) as it has purifying property, is 'akāya' (incorporeal) as it is devoid of distinguishing mark.
It is 'asnāvira' (without veins) as it is without the gross body, is 'kavi' (the knowledgeable) as it is omniscient, though becoming.
It is called the 'manīṣī', i.e. the wise one, as it is the lord of all minds, beginning with Brahma. It is lord of Prakrti as well. He is called the 'paribhūḥ', i.e. the omnipresent, as he is the best everywhere.
He, being the constant refuge of all, is called 'svayambhūḥ', i.e. self-existent and not dependent on others. He is called 'satya', i.e. truth, as he is indeed perceived as the flow of this everlasting real universe.
He is known as 'bhagavān', the lord, and 'puruṣottamaḥ', i.e. supreme among beings, as he is the creator and regulator of the beginningless and the endless time, that is in a single continuous flow.
Thus, the great Maha-Vishnu, having knowledge and bliss as his head, having knowledge and bliss as his feet (i.e. having knowledge and bliss as his body), created this beginningless and endless universe in reality, by his own will. Thus, he is called 'prabhuḥ', the Lord.
- stated thus in the Varaha Purana.
