This is what I did last night. I found it interesting, and saw value in sharing it.
I sat on the floor, cross-legged, and began by clearing my mind (not exactly an easy task for me). I chanted softly to myself- not anything in particular, just repeating a short line of made-up words I use for focusing. I grounded myself, picturing roots growing deep into the earth. I relaxed, and let my energy flow into the earth, taking with it all my stress and negativity. After several minutes, once there was nothing left to release, I started drawing fresh energy back up from the ground. This is all nothing new, I've done it a million times before, but on a whim I decided to try something different and incorporate the Chakras, or rather, my understanding of them.
Beginning at the base, I focused on drawing energy into my root chakra. While I was doing so, I meditated on some of the associations the root chakra has. I started with the elemental aspect, that of earth, because the elements were something I understood more readily. I concentrated on the feeling of the ground beneath me, and the heaviness of my body being pulled towards the ground by gravity. I imagined I was sitting on a slab of rock, and focused on the (imagined) feeling of the sun-warmed stone beneath me. I contemplated the issues of survival and stability, and felt a sense of security about me. After some time, I felt this chakra was "complete", and moved on.
For the sacral chakra I did much the same, starting with the elemental aspect (I imagined the feel of water softly misting down on me, then flowing over my lap as though I was sitting in a shallow river) then contemplating the more metaphysical aspects of the chakra. I did the same for the navel and heart chakras.
At the throat chakra, I focused on my chanting, and felt the universe resonate with each syllable. I felt reality itself, or at least the small bubble surrounding me, vibrating and undulating in response to my voice.
When I reached the third eye chakra I seem to have had some sort of shift in consciousness. I was no longer thinking or visualizing, at least not explicitly. I felt... a compression, I suppose, as though a vast amount of energy was being pulled into my body from all around. Time seemed both slower and irrelevant. My chanting, which had been growing faster and louder as I progressed through the previous chakras, became very slow and almost silent, although that could easily have been a change in my perception of it. My eyes were closed, but I could still clearly see the room as well as energy all around me, flowing, undulating, rippling. I felt a slight sense of anticipation, and a swelling of energy both without and within me.
I don't remember what exactly happened next, or whether I proceeded to the crown chakra. The next thing I recall I was dancing with my eyes closed. I felt exceptional, alive, powerful, vibrant. There was energy everywhere, brilliant white. It filled the room and I felt one with it. I danced, moving the energy all around. I felt euphoric.
A short time later I started to come down from this "energy high", and released all of the energy into the earth. I plan on repeating this experience tonight.
