Sutures and Sutras
The sutras for me, Wendy, the owner of WYoga have been sutures for spiritual and psychological injuries.
What are the sutras? There are many sutras. Karma Sutras, Yoga Sutras of Patanjali, the Bhakti sutras to name a few. Sutra means thread, in this case threads of wisdom. They are usually one line or two. The reason that the foundational texts for the sutras are, more often than not, lengthy is because the author waxes on about their unique view, translation of whichever ancient sutras they are writing about.
Needless to say, that as society evolves these translations or insights on the sutras change.
