“That which can possibly be harmful to the meditator is absorption samādhi(jhāna), the samādhi with deep, sustained calm. This samādhi brings great peace. Where there is peace, there is happiness. When there is happiness, attachment and clinging to that happiness arise. The meditator doesn’t want to contemplate anything else, he just wants to indulge in that pleasant feeling. When we have been practising for a long time we may become adept at entering this samādhi very quickly. As soon as we start to note our meditation object, the mind enters calm, and we don’t want to come out to investigate anything. We just get stuck on that happiness. This is a danger to one who is practising meditation.”
