@Arzack How do you know it is fast? Maybe it only works good for a few people?

Kriya is very firey. A less dangerous approach may be taking a whole body approach. Refining energy by circulating this through the body (micro cosmic orbit). Also known as qi gong. Dissolving all tensions until the qi (energy) can smoothly flow through the whole body. Much lesser complaints due to stuck qi. When the whole body overflows of energy , nice feeling, let it flow over to the head (and pop open the pineal gland). You can choose for healing Tao for this or even more watery (but maybe slow?) the water method for example given by Bruce Frantzis. Have an energized day!
