Sakyamuni Buddha told a great gathering:
"In full lotus sitting, the body-mind experience of samadhi, there is dignity that many respect. Like the sun lighting up the world, it clears away sleepy, lazy and sad states of mind. The body is light and tireless. Consciousness is also light and quick. Sit at ease, like dragons coiling! The king of demons is frightened on seeing even a picture of lotus sitting -- let alone a person experiencing enlightenment, sitting at ease without leaning or moving."
Thus, to observe just a depiction of lotus sitting makes the king of demons surprised, worried and afraid. Still more, when lotus sitting is really practised, its benefits are impossible to fathom. In short, everday sitting is happiness and good beyond measure.
Translated on the basis of the teaching of FM Alexander -- starting with the principle that sitting at ease is a very rare flower that can only blossom in the absence of fear of being wrong/trying to be right; and avoiding any mention of the word "posture" -- on the morning of 24th April 2008.
