The concept of the transcendent sphere is found in a variety of spiritual and philosophical traditions, but it is most commonly associated with Eastern spiritual traditions such as Hinduism, Buddhism, and Taoism.

In Hinduism, the concept of the transcendent sphere is referred to as “moksha” or “liberation” which is the ultimate goal of the human being, to achieve liberation from the cycle of reincarnation and merge with the ultimate reality or God.

In Buddhism, the concept of the transcendent sphere is referred to as “nirvana” which is the ultimate goal of the Buddhist path, to achieve the state of enlightenment and liberation from the cycle of suffering.

In Taoism, the concept of the transcendent sphere is referred to as “wu-wei” or “non-action” which is the ultimate goal of the Taoist path, to achieve the state of non-action and to live in harmony with the natural flow of the universe.

In other spiritual traditions such as Sufism, which is Islamic mysticism, the concept of the transcendent sphere is referred to as “fana” or “annihilation” which is the ultimate goal of the Sufi path, to achieve the state of annihilation of the self and to merge with the divine.

It’s worth noting that the concept of the transcendent sphere is not limited to Eastern spiritual traditions and can be found in other spiritual and philosophical traditions
