Is it possible to experience Kundalini awakening from the top down in your body?
It is possible to experience all types of Kundalini awakenings, top down, bottom up, left-to-right and right-to-left. It is possible to feel Kundalini rising in your extremities, at the top of your skull, at the back of your skull, in your stomach, in your chest, at the tips of your fingers and pretty much everywhere else in your body.
Those are physical experiences and they are all temporary. They follow the changes in your mind, dropping out of some of your unconscious beliefs, they do not precede them. It is, strictly speaking, utterly useless to focus on Kundalini rising, because in enlightenment, you dissolve into Kunda, the source of all Kundalini rising. But if you’re enchanted by Kundalini, you may want to experience it again and again, without much spiritual benefit. It will be just an experience, a trick of the mind.
Focus on the mind, the mind is dreaming, not the body. The body accumulates ticks and tensions from the dreaming mind, yes, but the body does not create the dreaming, the mind does. When you see through the dream of the mind and the mind starts to grind its dreaming to a halt, you might end up begging for less Kundalini rising, not more, so intense it will probably be, hehe.
