According to Osho, energy is not truly gathered in alternative bodily spots at all. The body is only a network of senses; when consciousness withdraws from the senses, you immediately stand apart from the body. The real 'collection' happens beyond the bodily circuitry, in bodiless awareness. So stop hunting for physical centers—separate attention from all senses, and energy naturally consolidates outside the body.
There aren’t special body spots to store energy; when you stop following your senses, your energy gathers by itself beyond the body.
