Yoga weakens the root causes of all suffering – the Klesas.
The Five Klesas listed in the Yoga Sutras are as follows:
1) Avidya – Self limiting thoughts, ignorance
2) Asmita – Ego
3) Raga – Attachment
4) Dvesa – Dislike, aversion
5) Abhinivesah – Clinging to life
Every type of suffering can be traced back to one of 5 klesas. Knowledge and awareness dispel them. Through the practice of yoga we can tune in, become aware and let go of the root causes of suffering.
