Whirling is as old as dance. Children naturally rotated around for fun and play.
The Great Poet ‘Rumi’ discovered it had many magical properties, and so a family lineage began of  ‘Whirling Dervishes’.

Q) How and Why can it help with Teleportation?

A) It’s a way to unify a paradox.  (movement & non-movement)

To spin one’s body in repetitive circles, without becoming disorientated, it’s first necessary to centre ones attention within their heart. Eventually after sufficient practice one can perceive themselves to be perfectly stationary in the midst of movement. Such a paradox is beyond the physical mind, thus this experience leads to an expansion, and embodiment of ‘integrated’ consciousness.
