Patanjali Yoga Sutra - II - 20

Check them with involution

Te Prati prasava heyaaha Sukshmaha
The five kleshas or impurities that cloud consciousness - Avidya, Asmita, Raga Dwesha, Abhinivesha - are present in a subtle state in the human mind. These five qualities can be subdued by the process of involution. This happens when the mind that usually spends its energies outside in the field of sense attachments to the world, closes in on itself and begins to look within the source of these five impurities which is consciousness.

Afraid to let go

Swarasavahi Vidushaha Api Tatha Aarudhaha Abhiniveshaha
First there is a false imagination that we have something - life to begin with, loved ones, property, name, fame, material possessions, beauty, good looks, knowledge....They are all travelling in us by their own force and essence. Particularly what we consider as our life, has a habit of preserving itself. Even the learned and the wise who have imbibed the non-duality of existence are not exempt from this fear. This fear of loss of life, loved ones, property and material possessions, name or fame, all born out of the primary delusion of Dwaita - two-ness - or a separate existence is unwarranted. It is a Klesha or an impurity which is a hindrance in the path of self-realisation. Practice of Kriya Yoga - Tapas, Swadhyaya and Ishwara Pranidhana (first Sutra of the second chapter) helps remove this impurity of the struggle to preserve and protect what doesn't belong to you in the first place. - Swahilya Shambhavi
