If

[Davka]

The people who participate in these festivals are normal people who during the year most of them eat meat and don't really do any meditation.
They follow Hinduism which involve a bit of chanting mantras and some prayers.
Once a year they want to prove themselves that God is with them so what they do?
3 weeks before the festival they only eat vegetarian food in order to clean up their body-mind from impurities and at the same time they chant mantras in the temples and sex is also off during that time in order to focus on the divinity within.

All of which results in a state of brain activity which causes the body to secrete natural pain blockers.

None of which leads logically to your conclusions:

When the time come their mind is therefore under control and their consciousness take over but here we got to understand that not everybody reach an high stage of consciousness so in some of them the mind still has some influence over them and that is why some of them feel a bit of pain and some scars are still visible while other feel no pain and no scars are visible so again you show that you haven't got the full picture of what really happen.

This is pure conjecture, based on a steaming pile of woo wrapped loosely in pseudoscience.

You have yet to demonstrate that such a thing as a "higher state of consciousness" even exists, let alone that the mind's influence over the individual can be halted without producing unconsciousness. All you're doing is parroting the explanations of ignorant snake-oil salesmen for things they themselves don't understand.
