1. Body Breathing: Feel the skin all over the body while following your breath. It is as if the sense of touch all over the skin senses the skin itself. Now feel that on the in-breath you expand out through the skin. On the out breath simply let go. An other way of saying it is that on the in-breath you feel the Shakti growing in intensity and size. On the out-breath you let go of any control and duality and merge with Shakti in and around the body. As you progress, you will discover the sense of Shakti becomes more tangible than the limits of the body; you expand. Do this as long as Shakti gets stronger and you merge more and more.
2. Spine Breathing: On the in-breath imagine you are moving energy up the entire spine at once, from the perineum to the top of the head. You can remember the word "shakti" as you breathe in. On the out breath sense you are radiating energy, or love-bliss, in all directions from the brain. You can remember the word "om" as you breathe out. The words are not important, the important thing is to get a good feeling of the flow of energy up the spine and from the brain. With a little practice the two phases will merge so that you on both the in-breath and out-breath sense the flow up the spine and the radiation from the brain. Do this as long as Shakti gets stronger and you merge more and more.
3. Inflow-Outflow (Void): Ignore the breath. Just sense love, bliss, Shakti, presence, Being, flow into you and radiate from you at the same time. It can be a little tricky imagining the two opposite directions at first, but once you get the knack of it, you will suddenly feel the double flow going on by itself and you may enter the void.
Merging in Love-Bliss; surrendering to the Self: When you experience being filled with Shakti or lovebliss, or Pure Being grabs you, then let go of your methods and merge with it. This is the goal of all practices and methods, so no matter what practice you are doing, if you are on the verge of transcending I-ness and merging, then let go of the method/practice and merge in lovebliss/Pure Being/Shakti.
Ending meditation: When it's time to end meditation, don't just stop and get up. First of all let go and see if you don't go deeper by letting go. Spend some time like this. Then open your eyes while staying in meditation. Or open and close your eyes a few times while trying to hold the meditative state. Then meditate a while with open eyes. Notice the difference in your state now compared to when you began meditating. Remember: we don't go out of meditation, because meditation is merging with the Self and we don't want to go out of the Self. We take the meditation into out daily life.
I took this meditation from a lovebliss. but you can find more Meditation Practice on Deep Meditation.
