I’ve read on the net at http://www.martialdevelopment.com/blog/experience-with-spring-forest-qigong someone claiming to quote Chunyi Lin as saying that 20 minutes of meditation in the Full Lotus posture is the equivalent of 4 hours in any other posture. Is this remotely true? I’m very inflexible in the hip joints now and I’m wondering whether to put in the necessary time and effort with yoga stretches to enable myself to do the Full Lotus safely and comfortably. Leaving aside the question of finding a physically stable posture for meditation, could I expect adopting the Full Lotus posture to significantly improve the effectiveness of my Small Universe meditation?
