The first creator (Brahma) knew the Supreme Person.
He in turn made him known to Indra (king of the gods)
for the benefit of all beings. Hence, even today he who
knows him and the creation thus, as pervaded and
permeated and possessed by this Supreme Person,
attains immortality. There is no other way for spiritual perfection.
