Interesting to read about your "star technique"... even more interesting is that in the same day i had read (in that link posted by Inferius) some techniques for extracting energy from things, and had tried it too. Coincidence?

My first attempt was toextract energy from the Earth. I lay down, relaxed, and started to visualize a flow of energy coming from the Earth and entering my back (as i was lying down)... i dont know if it was because i was focusing all my mind in this thought and therefore concentratingvery well, or if the technique works even in the first attempt... anyway, i felt VERY good... i wouldnt say i was "energized", but i felt a great well-being, and achieved a very deep relaxation.

Next day, i went to uni, stoned of course. My home is somewhat far from there, so the bus i take travels a lot until arrive there, and during the traject it goes near the sea. Then i tried to extract energy from the sea, and from the setting sun.
The bus was going westwards, so the sun was in front of me, and low in the horizon. Then i visualized the "energy" coming from the sea below me (i was in a large bridge) as small drops of water, rising, and passing through me. Also, i visualized the sun shining through me, and lighting this small drops, so they would reflect the light and shine, like small drops of transparent silver... it was a very beautiful image... and when i arrived at the uni, i was feeling very, VERY peaceful. It was a peacefulness different from i feel when i just smoke, so i know it wasnt caused by the weed. It was deeper, like if my innerest soul were calm and peaceful... it was very good and pleasurable.
And the mind image of rising drops of water, lighted by the setting sun was beautiful indeed...
