Hlw..while doing this exercise my body was shaking.. Heat & coolness is felt at the same time.. When I was blessings my family members I was crying.. And at the end I feel cosmic energy with the help of my finger tips was coming towards my shoulder…when I focus on my forehead my 3rd eye chakra is spinning…It was so awesome & peaceful kriya.. I feel so much peace… Then I became more calm & relax.. Its a beautiful experience.. When I took rest my lower (legs) were shaking..
