Acharya Prashant defines 'Vritti' as the emergence of forms and shapes within the empty, formless sky of consciousness. It is the illusion that something exists where there is actually nothing, and that this perceived existence is the truth. The root of all 'Vrittis' is the 'I-sense' or 'Aham Vritti', which gives birth to the world of facts, imaginations, and dualities like good and evil. He explains that 'Samadhi' is not a destination to be reached but our natural state of being like an open sky, which is realized only when 'Vrittis' are understood and dissolved. Liberation, or 'Nivritti', is described as becoming light by shedding the burden of all mental constructs, whether they are perceived as 'good' or 'bad'. The speaker elaborates on the five types of 'Vrittis' identified by Maharishi Patanjali: 'Pramana' (proof/reasoning), 'Viparyaya' (misconception/error), 'Vikalpa' (verbal delusion), 'Nidra' (sleep), and 'Smriti' (memory). He warns that 'Pramana' is the most dangerous because it anchors the mind in duality and the material world, preventing the leap of faith required to realize the Truth, which has no proof. He describes 'Viparyaya' as seeing a post as a tree, while 'Pramana' is seeing a post as a post; both are illusions because they rely on the 'I' to define them. 'Vikalpa' is living in empty words, 'Nidra' is a subtle state of mental emptiness that is not yet 'Samadhi', and 'Smriti' is the accumulation of past experiences that burdens the mind. To overcome these 'Vrittis', Acharya Prashant discusses 'Abhyasa' (practice) and 'Vairagya' (dispassion). 'Abhyasa' involves one part of the mind monitoring and resisting the other parts, powered by the strength of the Soul. 'Vairagya' is the realization that the 'clouds' of 'Vritti' only exist because we give them reality; it is the act of letting go. He distinguishes between ordinary 'Vairagya', which renounces the world, and 'Para Vairagya', which renounces the 'self' or the observer. Finally, he explains 'Samprajnata Samadhi' as a state where logic, bliss, and the sense of 'I' still exist but are directed toward the source, whereas 'Asamprajnata Samadhi' is the ultimate state beyond all dualities and descriptions.
