When there is no cause and effect then there is the non-dualistic reality.+

People who are stuck up with the creation & creator theory are unaware of the fact that they are worshipping the creation as God, not the creator.

The causality and creation, but are for religious people only. Religion is only for those who are unable to understand truth beyond form, time, and space. Religion is not final. It only gives satisfaction to the populace. Self-knowledge is for the whole of humanity to free people from experiencing the illusory birth, life, death, and the world as a reality.

Yoga Vasistha: ~ “The sun and the worlds become non-objects of perception, to those who have gone beyond the realm of objective perception and knowledge, even as lamps lose their luminosity while the mid-day sun shines.

From the standpoint of the formless Soul the ‘Self, the effect is non-different from the cause. However, in the realm of duality cause is different from the effect. The non-difference of the effect from the cause has to be grasped perfectly to realize from the ultimate standpoint there is neither the cause nor the effect because the cause and effect are one, in essence. That essence is consciousness.

Sage Sankara says: - If the cause is destroyed, the effect will no longer exist. For example, if from the effect, cotton cloth, the cause, threads, are removed, there will be no cloth, i.e., the cloth is destroyed. Similarly if in the effect, thread, the cause, cotton, is removed, there will be no thread, i.e., the thread is destroyed. (Brahmasutra Bhashya, commentary on the Brahma Sutra, (9) 2.1.9)

Despite the non-difference of cause and effect, the effect has its Self in the cause but not the cause in the effect. The effect is of the nature of the cause and not the cause of the nature of the effect. Therefore the qualities of the effect cannot touch the cause because the cause and effect are present only when the duality is present. 

The duality is present only when there is an illusion. 

The illusion is present only when there is ignorance. 

When there is no ignorance then there is no illusion. 

When there is no illusion then there is no duality. 

When there is no duality then there is no cause and effect. 

When there is no cause and effect then there is the non-dualistic reality.

Sage Sankara says: - During the time of its existence, one can easily grasp that the effect is not different from the cause. However that the cause is different from the effect is not readily understood. As to this, it is not really possible to separate cause from effect. But this is possible by imagining so. For example, the reflection of the gold ornament seen in the mirror is only the form of the ornament but is not the ornament itself as it (the reflection) has no gold in it at all. (Chandogya Upanishad Bhashya, commentary on the Chandogya Upanishad, 6.3.2)

All names and forms are real when seen with the Brahman but are false when seen independent of Brahman (Soul).

This way the seeker of truth establishes the non-difference of the effect from the cause.

In the context of Advaita Vedanta: ~ Jagat (the world) is not different from Brahman (Soul); however, Brahman (Soul) is different from Jagat

It has not been possible to preach Advaitic Truth entirely free from the settings of dualistic weakness it has not been more operative and useful to mankind at large because only a few will be able to grasp and realize it.:~Santthosh Kumaar.
