Ishopanishad: ~ “They are steeped in ignorance and sunk into the greatest depth of misery who worships the matter, instead of the All-Pervading God.+

All the orthodox Advaitins indulge and immerse themselves in a ritualistic-oriented lifestyle and follow the path of karma and Upasana which is meant for lower and middling intellect and not for realizing the Advaitic truth.

Many chose these orthodox scholars as their gurus. But these gurus are good for learning the conceptual Advaita meant for those Orthodox who believe their conduct-oriented lifestyle leads to Moksha [liberation]. the religious-based Advaita is not the means to acquire Self–knowledge or nondual wisdom.

Those who are seeking the truth have to do their own homework to acquire Self-knowledge or Brahma Gnana or Atma Gnana.

That is why Sage Sankara said:~ Talk as much philosophy as you like, worship as many gods as you please, observe ceremonies, and sing devotional hymns, but liberation will never come, even after a hundred aeons, without realizing the Oneness.

Vedas and Upanishads confirm the Soul, the Self, is present in the form of the Spirit or the consciousness.

Rig Veda: ~ The Atman (Soul or Spirit) 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)

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

Isa Upanishads indicates that: ~ “ By worshipping Gods and Goddesses and going to the world of Gods after death is of no use. The time one spends in ritualistic practices is wasted; one can spend the same time moving forward toward Self-knowledge, which is the main goal. One cannot reach the non-dual destination by glorifying God and Goddesses and by doing that, one goes deeper and deeper into darkness. It surely indicates the fact that the seeker of truth has to drop the worshiping God and Goddess to acquire  Self-knowledge.

Ish Upanishad says:~ people who do not try to attain Self-knowledge. They are, in a real sense, committing suicide, for what can be worse than being a slave to sense enjoyment, completely oblivious of the real purpose of life, which is to be one’s, own master?

Ish Upanishads:-

MANTRA 10

Vidya and Avidya both are hindrances to Self-knowledge, but Vidya is even worse than Avidya. The word Vidya is used here in a special sense; here it means worshipping Gods and Goddesses. By worshipping Gods and Goddesses you will go after death to the world of Gods and Goddesses. But will that help you? The time you spend there is wasted because if you were not there you could have spent that time moving forward towards Self-knowledge, which is your goal. In the world of Gods and Goddesses, you cannot do that, and thus you go deeper and deeper into darkness.

Avidya is Karma and therefore a hindrance. You perform Avidya - i.e., you perform Agnihotra and other sacrifices. This is a roundabout way of purifying the mind, and it is also groping in the dark. But it may not have as heavy a toll on your time and energy as the other.

Ishopanishad: ~ “They are steeped in ignorance and sunk into the greatest depth of misery who worships the matter, instead of the All-Pervading God and those who worship things born of matter like trees, animals, man, etc. are sunk deeper in misery."

It is necessary for the seeker to do his homework, and verify the validity of all the claims, rather than blindly believe, what others expound as knowledge, till; the un-contradicted truth is obtained. :~Santthosh Kumaar
