Yoga Quotes - page 14
In the Patanjali Yoga, five fundamental impurities are mentioned: avidya (nescience), asmita (ego), raga (attachment), dvesha (aversion), and abhinivesa (gross worldliness, craving).... They are klesas, very inadequately defined as defilements.... All that we have desired and thought have gone into making them. They are woven into the fabric of our emotions, desires, thoughts. They keep us bound down to a particular life-cycle. They are built up of samskaras, impressions accumulated over repeated births.
