There is no other reality than the phenomenal world and the phenomenal world exists only in the present. It is spontaneously brought about in the present by the interdependent origination or conditioned co-arising or universal relativity of all phenomena, called [madhyamaka-] pratityasamutpada in Sanskrit, which is the immanent incessant dynamic principle of existence. This means that the ingredients of what you call an ‘unmanifest potential’ must be sought amongst present phenomena and that your idea of it is merely a herenow mental deduction or extrapolation. A pre-cognition of unmanifest potentials would imply that they already exist in the future, which is an impossibility. (from advayavada.org/qanda5.htm)
