My meditation techniques ARE dangerous. In fact there cannot be any meditation techniques which are not dangerous. If they are not dangerous, they are not meditation techniques, they are tricks. Just like Transcendental Meditation of Maharishi Mahesh Yogi. They are mental tricks. Just consolatory. No danger. At the most they can give you good sleep, that's all. If you miss, you don't miss anything, you remain the same. If you attain, you attain to good sleep, that's all. No danger involved.
