Bhagwan’s divya mangal vigraha is of five types: Para, Vyuha, Vibhava, Antaryaami, Archa.

Whenever, it is said that Bhagwad swarupam is of five types, here swarupam means: swasya rupam. Swarupa here means swa asaadhaarana vigraha.

When we talk about divyaatma swarupa of Bhagwan, here swarupa means: swam rupam. Thus, Bhagwad swarupa would mean Bhagwan himself. He is always one. He is vibhu (present everywhere) and pervades every object without a gap, just like light pervades the glass.

That Vibhu, all-pervading bhagwan can’t be comprehended even by Nityas and Muktas. For the sake of anubhavams of jeevatmas, he takes bodies which are suitable for their anubhavam.

For the sake of nityas and muktas in Para loka, he takes the form of Para Vasudeva

For the sake of Devas including Rudra and Brahma, he takes Vyuha form.

For the sake of baddha jeevatmas, he takes various forms sajaatiya to them like trees, Mountains, humans, devas, fishes etc. These are called Vibhava avataras. He is present as Vishnu among Brahma and Rudra, Upendra among Devas and descended as Rama, Krishna etc avataras among humans.

For the sake of upasana-saukarya of Yogis, he appears as Antaryami in their hearts.

How does antaryami do niyaman of jeevatmas:

Who is the doer?Prakriti, jeevatma or Ishwara?

For the sake of all of the above mentioned (Nityas, Muktas and Baddhas), he takes the form of Archa avataras.

In all these bodies, Bhagwad aatma-swarupa is the same and thus there is no difference and no gradation possible. However, the gunas shown explicitly in all these are different and upasakas meditate on the different gunas in all the different forms.

NOTE

The important thing to note here is that Bhagwan is not of five types but his vigraham is five types. Bhagwan is always one only.
