The cosmic power lies in the navel of God. Hence, He is known as
Hiranyagarbha. Since He is full of divine effulgence and radiance, He is said
to be the very personification of beauty and splendour - Soundaryavanthudu and
Tejomayudu. The life of a human being is the noblest because he is endowed with
the principle of Hiranyagarbha.
God is also known as Prajapathi because He is the creator of the entire
universe. In order to understand the principle of divinity, you have to
understand the inner meaning and significance associated with each name of God.
God has various names, and each of them has a profound inner meaning. That is
why our ancients used to name their children by one or other of the names of
God.
