Aware is germanic, perceive is latin, it's the same concept. Maybe meditation doesn't have the results you think it has?
As for what drug experiences can tell us, I didn't claim they say anything about "the whole universe". They can however tell us other things. For one, LSD causes parts of the brain that usually work in a synchronised manner, like a system of cooperating parts, to loosen from each other, which is probably why one can experience a loss of coherence in perception of self and the immediate surroundings. At the very least it tells us that this molecule interacts with the biological foundation for experiencing the world as coherent, understandable, and when we're under its influence this experience is distorted or dissolved.
This tears into the feelings foundational to big religions, the perception of the universe as created, ordered, having a telos, can easily be temporarily disrupted, and hence we know that this 'wisdom' is contingent on us ignoring the possibility that it is a product of evolution rather than a divine gift or insight gained through spiritual exercise. You could of course project magical thinking onto such molecules and consider them demonic or whatever, but good luck keeping that up under capitalism without being victimised by conspiracy theory grifters, marketing specialists and so on.
