seventh plane. Other Indian interpretations Baba Hari Dass For Baba Hari Dass (a Maunisadhu monk who practices continual silence), evolution and involution are key concepts on universal level that have also individualized expressions in mental processes. In Samkhya and Yoga Sutras of Patanjali, in yoga practice, those two states are conditions of mind (chitta), with the mind's outward-evolution expressions (pravritti) and the inward-involution expressions (nirvritti). Nirvritti is the involution stage where "Yoga is the control of thought waves in the mind" (Sutra 2, Samadhi Pada). Outward expressions of mental activity, vritti, draw the mind to the afflicting experiences, and in effect produce afflicting impressions of klishta-vritti, or vyutthana samskaras (outgoing mind). Involution, or deep introspection in yoga, leads to the opposite results and attenuates afflicting impressions to the finest degree possible with the end result of aklishta-vritti (non-painful thought waves). Thus, when the mind is liberated from painful impressions, one-pointed mind (ekagra samskara) is achieved, which can be said to be the goal of yoga. One-pointed mind is the foundation of samprajnata and asamprajnata samdhi, or "super-consciousness". Integral thought In integral thought, involution is the process by which the Divine manifests the cosmos. The process by which the creation rises to higher states and states of consciousness is the evolution. Involution prepares the universe for the Big Bang; evolution continues from that point forward. The term involution comes from the idea that the divine involves itself in creation. After the creation, the Divine (i.e. the Absolute, Brahman, God) is both the One (the Creator) and the Many (that which was created). The integral philosopher Ken Wilber refers to involution in his online chapter of Kosmic Karma, employing concepts from Plotinus, Advaita Vedanta, Tibetan Buddhism, and Sri Aurobindo. According to Wilber, the cosmic evolution described in his previous works is preceded by an involution of Spirit into Matter. This involution follows the reverse stages to the sequence of evolution—e.g. Spirit to soul to mind to life to matter. Once the stage of insentient, lifeless matter is attained, then "something like the Big Bang occurs", whereupon matter and manifest world come into concrete existence, from which stage evolution follows. Gurdjieff Involution and evolution are important themes in the cosmology of G. I. Gurdjieff (1866? – 1949), addressed in detail in his book Beelzebub's Tales to His Grandson. In a popular presentation of Gurdjieff's teaching by P. D. Ouspensky and others, different terminologies
