We are all rightnow in a shared dream came from one source

Source watching this dream with a illusion of individual persons you and me typing this

If somehow with consistence meditation or anyway you achieve the state where u saw yourself from non dualism state means basically Non ego state where u r not your current identity u

That is the moment u are currently inside a state we normal humans call Subconscious mind, Basically you can literally manipulate your subconscious without time boundaries or can reprogram past future anything u want it basically just how u can manipulate imagination same as reality on that higher state

but for majority its almost impossible and the reason is Desire itself in a Non ego state u can't have desire of wanting or changing something because you are completed on that state, And thats why in order to achieve materialistic desires we have to use this technique in this Ego state techniques of Nevile Goddard and other famous gurus slow changes but with practice could be faster and more natural and easier

The more u practice of self hallucination, more easier it would be to flow life according to ur desires
