The fertile field for impurities
Avidya Kshetramuttaresham Prasupta Tanu Vicchinna Udaranam
Anithya Ashuchi Dukha Anatmasu Nithya Shuchi Sukha Athma Khyatihi Avidya
After outlining the five impurities, in these two Sutras, Patanjali says that Avidya or ignorance is the root cause for all the other four impurities.
In the fertile soil of Avidya, a conducive atmosphere is presented for the sprouting of the sapling of Asmita or the "I, Me, Myself," ego, the attachment of people, places, things and situations born out of that ego, hatred to all that doesn't act in conformity with this ego and finally an effort to preserve this false and non-existent ego are the impurities in consciousness born out of Avidya. These impurities are almost non-existent, dormant, lean, thin and weak. They express sometimes in fits and starts or are fully active. The fully active cases of these Kleshsas is what we see manifested in today's world of terrorism, killing, violence and gore.
The next sutra explains what Avidya is. Confusing or mistaking the impermanent, impure (mixed qualities), the sorrowful and material for the permanent, pure, pleasurable soul is Avidya. To quote an example - the human body and mind is impermanent - it is born and goes through phases of transformation and dies. It is impure in the sense, it is not one homogenous composition, but a mixture of matter and thoughts of innumerable frequencies ofr vibration. They are afflicted by sorrow. It is non-spirit by its sheer gross eistence. Taking this body and mind to be the permanent, pure, blissful soul is Avidya. Though the hand writes, we say, "I am writing," confusing the soul "I" here with the body. Knowledge or Vidya is a 24/7 understanding that we are the one indivisible soul and this body and mind are tools for its expression. - Swahilya Shambhavi (Pic.
