God in truth is the cause of the illusory form, time, and space, and God in truth is causeless.+

In a dream, the man and the world are dream objects and all actions and thinking are happening. If one is the dream entity, there must be a dreamer.

The formless witness witnesses the dream in which man and his experience of the world are present. 

Thus, the dream is an object to the formless witness. Similarly, man and his experience of the world, his actions, and his thinking are happening within the waking experience. Therefore, there is no difference between waking and dream.

The witness of the three states is within and it is formless and apart. It is within as the formless substance of the three states and it is apart as the formless witness of the three states. It has nothing to do with the waking and dream entity because it is the witness of the whole waking or dream entity.

The dream becomes unreal when the waking takes place. When the Advaitic wisdom dawns then the waking experience becomes unreal. 

Advaitic wisdom dawns when the waking entity realizes the fact that, it itself is not the self but the self is formless Soul, which witnesses the coming and going of the three states without the physical apparatus.

In the dream world, the dream people appeared together and disappeared together and disappear together. Similarly, the waking world and waking people appeared together and disappear together. 

Thus, the dream is created out of single stuff and that stuff is the Soul, which is present in the form of consciousness. In the same way, the waking experience also created out single stuff. And that single stuff is the consciousness.

The Soul, which is present in the form of consciousness is the cause of the three states and it itself is uncaused. The many Souls theories are religious and yogic fable based on the false self(ego) and false experience (waking).

Knowledge of the single stuff is Self-knowledge or Brahma Gnana or Atma Gnana

Like an ornament made from gold is gold, that which is born out of consciousness is consciousness. Like gold is the permanent thing, in ornaments made of gold, similarly, the mind, which is in the form of the universe is born out of consciousness, is consciousness in its essence.

The Soul is the ultimate truth or Brahman or God in truth. God in truth neither comes nor goes, but God in truth exists always. The form, time, and space, which appear as disappears are mere an illusion. Thus, all the form-based Gods are merely an illusion. God in truth is the cause of the illusory form, time, and space, and God in truth is causeless.

Why worship God based on the illusory form, time, and space, Self-realization is God-realization and God-realization is the real worship. 

Remember:~

Satsanga is thinking and reflecting on the ultimate truth or Brahman or God in truth. The Soul, the Self is the ultimate truth or Brahman or God in truth.

Brihadaranyaka Upanishad: ~ Brahman (God) is present in the form of the Athma, and it is indeed Athma itself.

Even Rig Veda: ~ The Atman 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)

To be aware of the Atman or the Soul at all times is Satsanga.

Constant reflecting on the nature of the Soul is Satsanga, or association with Gnani is Satsanga.

Satsanga is neither hearing the sermons of the Gurus or priests nor indulging in religious activates nor hearing the stories of mythological stories by Swamis nor reading biographies of Saints and Sages nor intellectual discussion but Satsanga is to discover and realize the truth of our true existence.: ~ Santthosh Kumaar
