I have experinced it quite a few times in past many years.
Only for a fraction of moment, but very much physical experince.
A wave of cool energy from a point in front of face. A moment of bliss and then its gone. Its such momentary normally I always ignored it. There are many other intense experiences that actually shadowed this one simple thing.
But its always in a rare moment. Never repeats even if I searched for.
Some years back, the Morning Kirtan in ISKCON temple.
May be once during the very beginning of the energy body initiations.
Then once at a Book fare when a Monk Greeted and invited to the temple's shop.
The point is like may be a inch in front of nose close to the nitch of the upper lip.
I feel a energy point of World of Perception. right here. Inactive.
There are some meditation techniques that are actually based on focusing on the tip of nose and connecting to God conciousness. There is some of this kind of meditation in Vaishnavism.
I took some time, to try finding the feel again. Its more like a fan giving air to your face. while its just some energy flow activating at this point.
The first name in my mind. is the code..."Chaitanya Kriya"
Experince the activation. and yes please fill the feedback form in later 2-3 days and mail.
