The rituals mentioned in the Karmakanda of Vedas are sought to be negated in the Jnanakanda, which is also part of the same scripture.+

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

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. 

Sage Sankara pointed out that those rituals could in no way bring about wisdom, much less Moksha.  

The rituals mentioned in the Karmakanda of Vedas are sought to be negated in the Jnanakanda, which is also part of the same scripture. While Karma kand enjoins upon you the worship of various deities and lays down the rules for the same, Jnanakanda constituted by the Upanishads ridicules the worshiper of deities as a dim-witted person no better than the beast.

The path of wisdom is divided into three parts:~

First: hearing the truth--that consciousness is the only reality and that the universe along with you is merely an illusion or Maya.

Second: reasoning upon these words of wisdom of Sage Sankara from all points of view.

Third: giving up all further argumentation and realizing the truth. This realization comes from being certain that consciousness is the ultimate truth or Brahman or God in truth.

Remember:~

Rig Veda: ~ 'Prajnanam Brahma'- Consciousness is the ultimate reality or Brahman or God in truth.

God in truth is the Atman, the Self. Atman is present in the form of consciousness. Do not accept any other God other than Atman not worship other than Atman. Let these words be inscribed in your subconscious.

Nothing is real but God. Nothing Matters but love for God in truth. God in truth is everywhere and in everything.

God in truth is hidden by the illusory universe. God in truth alone is and all else is an illusion.:~Santthosh Kumaar
