Previously, Shri Krishna spoke about Ishvara as the cause of several subtle expressions including non-injury, penance and so on. He now enumerates Ishvara’s manifest, visible expressions. Per tradition, the entire universe was created by seven great sages and fourteen individuals known as “Manus”. Shri Krishna asserts that these sages and Manus, the creators of all living and inert beings in this universe, were themselves created by Ishvara through his mind.
The Srimad Bhagavatam described the creation of the universe in great detail. Ishvara first created Lord Brahma and entrusted him with the responsibility of creating the universe. Lord Brahma then created the four child-sages Sanaka, Sanandana, Sanaatana and Sanatkumaara. When he asked them to populate the world, they refused, because they did not want to get tangled in any material pursuits. They took the vow of celibacy and roamed the world, constantly contemplating upon Ishvara.
Next, Lord Brahma created the saptarishis or the seven great sages Bhrigu, Marichi, Atri, Pulastya, Pulaha, Kratuhu and Vasishtha. He then created Manu was who was entrusted with further procreation and establishment of the moral code, which is known as Manusmriti. There are fourteen Manus that correspond to fourteen Manvantaras or periods of Manu.
Having enumerated the creators of his universe, Shri Krishna says that all those original individuals are expressions that were created from Ishvara’s mind, just like we create whole new worlds in our dreams in a matter of seconds without any external materials. This shloka is similar to the biblical verse “Let there be light”. The idea is the same – that Ishvara is the original cause of everything.
What is the result of knowing Ishvara’s vibhootis or expressions? This is given in the next shloka.
