Religion is based on the ego whereas Spirituality or Adyathma is based on the Soul, the Self.
Vedas and Upanishads confirm the Soul, the Self, is present in the form of the Spirit or 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)
Bhagavad Gita: ~ Brahmano hi pratisthaham ~ Brahman (God in truth) 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, that God is considered the all-pervading consciousness which is the basis of all the animate and inanimate entities and material then nothing has to be accepted other than consciousness
Religion propagated and led people to believe strongly that the mycological actually existed.
The religion's fictional character is made up to give followers of the religion founded in the name of mythological Gods and Goddesses as icons worthy of their worship.
Even if you come through the Vedas there is no mention of the mythological.
All these mythological Gods are not Vedic Gods. Propagating mythological Gods as Vedic Gods is propagating myth as truth.
In the past mythological Gods were introduced by some saints and founders of castes because people were not capable of an unknown God without a form and attributes.
Bhagavad Gita: - All those whose intelligence has been stolen by material desires, they worship many Gods. (7- Verse -20)
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. God in truth is only Atman, the Self’.
In reality, there is no duality, no differentiation. Only Atman exists.
Thus, by sticking up to the Gods, which are not God in truth, you are sticking up to the illusion.
Sticking up to illusion means sticking up to ignorance. sticking up to ignorance means you are not qualified to acquire Self-knowledge or Brahma Gnana or Atma Gnana.:~Santthosh Kumaar
