Hinduism advocates God as A Principle,Beyond Attributes.

The underlying principle of Life and Universe,both known and Unknown lies in all these,they in It,yet It is beyond them.

It is the Reality,Brahman.

This Brahman is without beginning and end.

It is Infinite.

It is beyond words,thoughts.

It Immanent and as well all Pervasive.

It can be felt and Realized.

There are various methods tried to Realize Brahman,also known as the Self.

There are as many paths,methods to Realize Brahman as many individuals and individual dispositions are.

To understand this principle and realize Brahman as a Priniple,Beyond Attributes is possible only for a few.

Brahman is Realized and not Known in the manner of our knowing mundane things.

It is,for short of words, I use this term, Experienced.

Experiences,all of them need not be through our sense organs alone.

However as this understanding of Brahman as Principle,Hinduism has suggested the method of Realizing Brahman through worship of Personal God,called Easwara.

Please read my article on Iswara Pranidhana,Yoga.

In this method God is related as Preceptor,Father,Mother,Guru,Friend,Lover……

The mind relates to things it likes.

So one is advised to choose the Devatha as he pleases,in consultation with a Guru,who can guide him in choosing what is best .

This worship of Personal God is called Saguna Aradhana,while the realization process of Brahman as The Absolute is called Nirguna Aradhana.

According to Vedas,the authority for Hindus on Spirituality,Saguna Aradhana leads to Realization.

Many Gods are found in Hindu traditions because of this thought,though the substratum of all is,One.

Among many Gods/Goddesses,three are called the Trimurthis,the Trinity.

Brahma,Vishnu and Shiva,representing Potential,Kinetic and Potentio-kinetic energy respectively.
