Time has existence only with reference to relativity. The Absolute is Changeless and hence Timeless, as it is not related to anything. But only because of this Timeless Truth, we can know the relative time. So the changeless Supreme Truth is in the inner core of all beings as the Self and in the outer periphery as Time, whom we call God.

Bh. 3.26.20 – 21

Bhagavatham describes Purusha and Prakrithi as “man and woman” and their union gives birth to their first child Mahath Thathwam – this is the seed of the tree called world. As all the parts of a tree like its trunk, leaves, flowers etc. are contained in its seed, this Mahath Thathwam contains the entire world in it. Mahath Thathwam shining by itself (like a Sun) dispelled the darkness that surrounded it.

The first Swaroopam of Mahath Thathwam is Chitham. When it is devoid of all stains of impurities and hence the purest (in the absence of likes and dislikes) and the true means to know the Lord, it is called Vasudeva.

The Mahath Thathwam is divided into Chitham, Ahamkaram, Manas and Budhi represented by Vasudeva, Sankarshana, Anirudha, and Pradyumna respectively.
