I agree that I cannot claim to know much about Quantum Mechanics. Polymath knows. I would be very happy if he responds to my post. Meditation, as per my view, is just concentrating on what is to be contemplated. 'Why it is so?' There are other views among religionists that meditation gives you the key of some 'universal truth' or, by awakening one's kundalini, it will give you the power to fly wherever your mind goes (Siddhis). Being a strong atheist, I do not believe in such clap-trap.
But, if you would see, getting into Quantum Mechanics is very easy for one who thinks clearly. The question is 'Wherefrom all that exists arose?' There were two options for the Hindu philosophers - 1. It is eternal (Much like God is beyond physical domain). The reason 'Why is it eternal?' not given. 2. The other option was 'Creatio Ex-Nihilo'. Here one does not have the problem of explaining the source of origin. So, on one hand we have existence, on the other we have non-existence. If there was some relation between existence and non-existence, then it solves the problem. For this reason, 3,000 years ago, the poet of the famous Hindu Hymn of Creation (Nasadiya Sukta), said two things:
1. 'Sages who searched with their heart's thought discovered the existent's kinship in the non-existent.'
2. 'The Gods are later than this world's production. Who knows then whence it first came into being?'
