The practice of yoga has a long, complex history and deep ancient tradition as an integrated lifestyle science (Bhavanani, 2011). Those who have practiced yoga in its full form, including the eight traditional steps of yoga philosophy, find that touches almost every aspect of their life in mental, physical, emotional, psycho level. The purpose of this paper was to study the philosophy of yoga. More specifically was analyzed “niyamas” (the second of the eight steps of yoga), “yamas” (the first of the eight steps of yoga), their relationship and application in modern life. Also was analyzed the relationship between “niyamas” with the rest steps of yoga. In conclusion, “niyamas” and “yamas” are ethical, moral, introspection, and discipline commitments that create a solid background for the transition to deeper levels of concentration and inner strength. They are the fundamental nature of yoga and should be practiced equally to the rest steps (asana, pranayama, pratyahara, dharana, dhyana, samandi) for an integrated practice. All eight steps of yoga are important and necessary. Yoga and her complete practice has been proved multiple emotional, mental and physical benefits. Yoga improves quality of life and wellbeing indicators.
