When non-dual wisdom dawns, than the universe[duality] becomes mere mirage created out of consciousness. The duality is present only when the universe is present. If the universe is mere mirage than the duality also is mere mirage. Thus all the illusory bonds of duality brakes and the ‘self’ is liberated from the clutches of duality which was experienced as reality. Same way as dream becomes unreal when waking takes place the duality becomes unreal when wisdom dawns.
Many think that it is worthwhile to acquire the miraculous powers through practice of yoga and mystism which in turn help him to create whatever they want wants in practical life.
When the waking experience itself is an illusion than what is the use of miracles performed within the illusory experience. Whatever is based and performed on the base of ego is bound to be part of the falsehood. Hence miracles are part and parcel of illusion.
Until and unless they make sure 'I' is not self and world is unreal through deeper self-search they are bound to believe their intellectual accumulated knowledge as wisdom. The wisdom is knowledge of the reality which is beyond the form, time and space.
Philosophical and scriptural knowledge which are based on ego as self are not useful in pursuit of truth
