Kundalini meditation

 It's basically focusing your spiritual energy through your chakras. The idea is to feel warm. Close your eyes, and as you concentrate on the inside of your chest, imagine the chest and you'll start to feel warmth. That warmth is what you want. Don't close your eyes, unless you have to, where your a beginner.

 Once you discover it, your goal is to get it to spread as much through your body as possible. It takes less thought to activate, yet is more effective than normal meditation. That heat basically unlocks all your chakras and energy networks. Even better is you don't have to find a quiet place to do it. As long as you know how to summon the internal heat, you can do it anywhere. The trick is to get it to take over all of you. When the heat doesn't reach somewhere. Then, that area is blocked at the chakra point. Force the heat to be there and beyond, if necessary. You can open your chakras up, using this technique.
