2. Prajāpati [i.e., Virāṭ] thought about the worlds [he would have]. Out of his thinking, the three Vedas took shape. He then began to think about the Vedas. As a result of this thinking, the Vedas gave birth to the three vyāhṛtis: bhūḥ, bhuvaḥ, and svaḥ.
Prajāpatiḥ lokān abhyatapat, Prajāpati meditated on the worlds; tebhyaḥ abhitaptebhyaḥ, from [the worlds] which he meditated on; trayī vidyā samprāsravat, emerged the three Vedas; tām abhyatapat, [Prajāpati] meditated on them [the three Vedas]; tasyāḥ abhitaptāyāḥ, out of [the Vedas] which he meditated upon; etāni akṣarāṇi, these akṣaras [syllables]; samprāsravanta, emerged; bhūḥ bhuvaḥ svaḥ, bhūh, bhuvaḥ, and svaḥ; iti, that is all.
How can you attain liberation? You can attain it when you surrender everything for its sake. To make this clear, the story of how the world came into being is narrated:
God (or Virāṭ, or Kaśyapa) created this world by practising austerities. What kind of austerities? He simply planned the creation in his mind. This planning, this mental exercise, is enough austerity for him. And as thinking is doing for him, whatever he thinks immediately comes into being. The worlds emerge from within him. The first to manifest, however, were the three Vedas: Ṛk, Yajuḥ, and Sāma. When these emerged, the Creator thought about them, and from the Vedas came the three vyāhṛtis (lit., utterances): bhūḥ, bhuvaḥ, and svaḥ.
Then from these came Om, the symbol of Brahman. If we concentrate on Om, we attain Brahman. But we have to surrender everything for the sake of Brahman. This is the conclusion to be drawn from this story. Even the Creator has to concentrate on what he is going to create, and he has to surrender everything else.
