At its core, tantra which I have seen defined as “expansive weaving” (as on a loom) is about our connection with Spirit; not just as a means of heightened sexual pleasures, but perhaps enlightened sexual pleasure.
There is a strong misconception about negative energy and positive energy. Most believe negative energy to be “bad” and positive energy to be “good”. However, negative energy is really the LACK of energy. Positive energy is an abundance of energy. Negative energy takes and Positive supplies. Negative people are the takers and drainers and positive people are the givers and receivers.
