Sage Sankara’s Brahman or God in truth is impersonal. Worshiping personal Gods is meant for the orthodox people who are ignorant and refuse to accept the truth.+

If people have believed religious propagated myth thing over thousands of years, the length of time does not prove it true.

You are being conditioned by the religious myth which has made you a non-thinker. Come out of the religious myth by realizing God in truth.

The religion blocks one from realizing God in truth because religion is based on myth whereas Spirituality is based on the truth.

Spirituality is nothing to do with religion. Spirituality is based on the Spirit, the real God whereas religion is based on the false self within the false experience. 

The Spirit is the root element of the universe. The Spirit is present in the form of the Soul, the innermost Self. The Soul is present in the form of consciousness. From the Spirit, the universe comes into existence. In the Spirit, the universe resides. And into the Spirit, the universe is dissolved. The Spirit is the parent of all that is there is. 

Sage Sankara's Advaitic wisdom is pure spirituality or Adyathma.

Sage Sankara’s  Brahman or God in truth is impersonal. Worshipping personal Gods is meant for the orthodox people who are ignorant and refuse to accept the truth. 

Sage Sankara clearly says:~ Neither studying philosophy nor by worship as many gods nor observe ceremonies nor by singing devotional hymns nor by uttering mantra nor by mastering the sciptures liberation comes without realizing the Oneness.

God in truth is not based on your inherited blind faith or belief. The Religions are based on personal God whereas Sage Sankara’s Supreme Brahman (God) is impersonal, Nirguna (without Gunas or attributes), Nirakara (formless), Nirvisesha (without special characteristics), immutable, eternal, and Akarta (non-agent). God is above all needs and desires. God is always the Witnessing Subject. God can never become an object as God is beyond the reach of the senses. God is non-dual, one without a second. God has no other beside it. God is destitute of difference, either external or internal. God cannot be described because description implies a distinction. God cannot be distinguished from any other than God. In God, there is no distinction between substance and attribute. Sat-Chit-Ananda constituted the very essence or Svarupa of God, and not just God attributes. The Nirguna Brahman of Sage Sankara is impersonal.

Remember:~

Bhagavad Gita itself says: ~ Brahmano hi pratisthaham ~ Brahman (God) is considered the all-pervading consciousness, which is the basis of all the animate and inanimate entities and material. (14.27).

When Bhagavad Gita says, God is considered the all-pervading consciousness which is the basis of all the animate and inanimate entities and the material then nothing has to be accepted as God other than consciousness. 

Lord Krishna Says Ch ~V: ~ “Those who know the Self in truth.". The last two words (tattvataha) are usually ignored by pundits, but they make all the difference between the ordinary concept of God and the truth about God.

The dualistic worship of "God” is only for the ignorant populace. The God in truth is only Atman, the innermost Self.   In reality, there is no duality, no differentiation. Only Atman exists.

Bhagavad Gita Chapter: ~ “All those whose intelligence has been stolen by material desires, they worship many Gods. (7- Verse -20)

The Vedas confirms God is Atman (Spirit), the Self.

Rig Veda: ~ The Atman is the cause; Atman is the support of all that exists in this universe. May ye never turn away from the Atman, the  Self. May ye never accept another God in place of the Atman nor worship other than the Atman?" (10:48, 5)

How can you worship God? That implies two ~ the worshipper and the worshipped, whereas the God is nondual. One can worship his idea of God only or realize his unity with it when he can’t worship it as apart.

Kena Upanishad (6) Chapter I: ~  “That which cannot be apprehended by the mind, but by which, they say, the mind is apprehended-That alone know as Brahman, and not that which people here worship.

Kena Upanishad (7) Chapter I:~  That which cannot be perceived by the eye, but by which the eye is perceived-That alone know as Brahman and not that which people here worship.

Kena Upanishad (8) Chapter I:~  That which cannot be heard by the ear, but by which the hearing is perceived-That alone know as Brahman, and not that which people here worship.

Kena Upanishad (9)- Chapter I:~ That which cannot be smelt by the breath, but by which the breath smells an object-That alone know as Brahman, and not that which people here worship.

Even in the Brihadaranyaka Upanishad: ~ Brahman (God) is present in  the form of the Athma, and it is indeed Athma itself’.

Thus, it clearly indicates the God is without the form and attributes and ever free.  

When Upanishads and Vedas declare that, “God is present in  the form of the Athma, and God is indeed Athma itself” then why accept another God in place of the Atman or worship other than the Atman. : ~ Santthosh Kumaar
