Psychophysiological analysis of Kriya Yoga as per Patanjala Yoga Sutra

Background: Kriya Yoga that includes Tapas,vadhyaya, and Ishwara pranidhana as given by Patanjala Yoga Sutra finds its mention twice in the text as Kriya Yoga and as Niyama. The double occurrence has significance. Aim: The aim of this work is to carry out an analysis of what Kriya Yoga is, what is the purpose of repeating three components of Kriya Yoga, i.e., Tapas,vadhyaya, and Ishwara pranidhana in Sadhana pada. Method: The three steps of Tapas,Svadhyaya, and Ishwara pranidhana were analyzed in detail. The important difference of this analysis from other commentators is to analyze the first two steps of Kriya Yoga from the psychophysiological point of view. Analysis: The Kriya Yoga brings psychophysiological changes leading to the total control of the body, i.e., internal functions of the body. It also leads to surrender to the internal supreme existence of one's own being. The process of Tapas, Svadhyaya, and Ishwara pranidhana, as per Kriya Yoga, converts a common person into a yogi. Conclusion: The process of Kriya Yoga facilitates the removal of resistance within i.e. preparing condition of chitta which is necessary for entering into Samadhi is fulfilled.
