The religious orthodox wants to wage against modernity: secularism, science, reproductive rights, and the Enlightenment generally. The orthodox mass, argue that any and all problems with the world can be attributed to the groups and ideas which they most dislike. One of the worst aspects of this attitude is how some religion latch on to any tragedy to promote their theocratic vision. Every religion argues that only their religion and their god can cure whatever ails this world. Such blind belief of religion blocks people from knowing the ultimate truth or Brahman.
History speaks that man has made it challenging and difficult to understand why he has experienced and witnessed such an array of human behaviour. With constant introspection and the continued judgments of right and wrong, good and bad, just and unjust it has been a constant challenge to find and understand the truth behind his physical existence. This subject is super sensitive, yet if one is to continue on his pursuit of truth then there is a need for perfect understanding and assimilation. There is need to stop this wars and violence, which is going on in the name of religion and god, by knowing and understanding and realizing the universal truth, which is holding the whole universe in which the humanity exists. The universal truth alone is god all else is mere mirage.
In Vedas the God has been described as:-
v Sakshi (Witness)
v Chetan (conscious)
v Nirguna (Without form and properties).
v Nitya (eternal)
v Shuddha (pure)
v Buddha (omniscient)
v Mukta (unattached).
So, it clearly indicates that god is formless thus there is no scope for form based god. The religion and its idea of conceptual gods, and its theories of karma, haven, hell, papa, punya, rebirth, reincarnation are based on the false self, within the false experience. Therefore, they are meant for lower mind-sets, they are of no use for those who are seeking higher truth as indicated in the scriptures.
There are many schools of thought in Hindu religion based on Vedas. These schools of thoughts are add-ons based on dualistic view point. Therefore, these add-ons have to be bifurcated from original Vedic Religion, to get the pure Vedic essence.
Sri, Sankara said: The world is unreal and Brahman alone is real. It means the birth, life and death, which happens within the world, also is unreal. If birth, life and death are unreal, then the rebirth and reincarnation and Avataric concept has to be unreal. Thus, it is for the seeker to find out, on what standpoint the world becomes unreal, to know the Brahman, which is ultimate truth.
Causality taught in the Upanishads is only to enable us to understand the supreme truth of no-origination. The world is not different from the self and the self is not different from Atman and Atman is not different from Brahman. That the non-dual absolute appears as the diverse world is only an illusion. If it really became diverse then the immortal would become mortal.
The dualists who seek to prove the origination of the unborn, by that very enterprise try to make the immortal, mortal. Ultimate nature can never change - the immortal can never become mortal and vice versa.
Gaudapada quotes from the Upanishads:- "There's no plurality here"; "The Soul through its powers appears to be many"; "those who are attached to creation or production or origination go to utter darkness"; "the unborn is never reborn, for what can produce it?”
