Kundalini meditation is a kind of meditative technique which is designed to tap into your capacity for 'love' and your libido. While meditation techniques – and even the end goal of meditation – can vary widely, they all are essentially aimed at directing and controlling our own thoughts so that we can learn about ourselves, increase concentration, and often relax; with kundalini meditation the focus is simply on that sexual and loving energy also described as 'pure desire'. By focussing simply on this you can then increase your own pleasure and passion. At the same time though there is of course a deeper philosophy, with this 'pleasure' sensation supposedly being the genuine 'spirit' of mankind. This is thought of as the natural self, and to release it is supposed to lead to self-realisation and nirvana.
This energy is supposed to be released by a 'guru', and the body should be prepared by physical exercise, breathing exercises (pranayama), visualisation and hatha and forms of yoga – of course it can also be awakened by meditation. Sometimes it is said to awaken naturally with no obvious reason.
Interestingly the term 'kundalini' actually means 'coiled' in Sanskrit, which has a lot to do with the visualisation techniques employed in kundalini mediation. That is to say that the kundalini is visualised as a coil, often a snake, at the base of the spine. Sometimes it can also be visualised as a Goddess or a pink 'bubble'. By getting yourself into a meditative state through a comfortable seating and breathing exercises to clear the mind, you can then begin to focus completely on that visualisation and the feelings of love that you can imagine 'radiating out of it'.
The visualisation however is not important. What is important is the ability to focus on this point and to try and use it to 'feel' the impulses of love and desire and sexual energy. Imagine it radiating out of the base of your spine and filling your body – washing you in love. Some people will then move on to think of a person that they really love and/or desire in their life – and to really focus on the feelings that person creates and then intensify them. This can strengthen your relationship in the long run, and bring about intense feelings of desire and love in the short term that will be highly pleasurable and enjoyable. It is our thoughts that control how we feel and that dictate and define our experience, so by bringing about such strong thoughts and feelings of love and passion we can experience this kind of bliss on demand.
