Around 400 BC, Maharishi Shri Pátañjali codified in sutras (aphorisms) the process leading to the enlightenment of consciousness (Samádhi), known as Yoga. Iyengar also emphasizes the practical aspect of Yoga, which Westerners often have a difficulty to grasp. We are oriented towards mental activity, and clarity seems to be confined to what is conveyed through words. However, a comprehensive study of the Yoga Sutras reveals a purpose and meaning behind the union signified by this term:The purpose of the union of Purusha and Prakriti  is the realization, by Purusha, of its true nature and the unfolding of the inherent powers within both Purusha and Prakriti".The reference to this union reveals an apparent division between Purusha and Prakrti. However, let us revert to the concept of union to elucidate how yoga facilitates this union and thereby sheds light on why this practice brings benefits to physical and mental health. To achieve this, I intend to expound on the philosophical conceptions presented in the Vedas, which find an update in the works of Sri Aurobindo. Utilizing his work renders these concepts more comprehensible to the modern audience, as this author contemporizes them and acquaints us with the transformations and adaptations that have occurred over time. These conceptions primarily revolve around a transcendent Absolute, which, according to this author, transcends mere abstraction and becomes a palpable reality, sustaining our entire world, and closely aligning with the concept of causality. My objective here is to indicate the practices that lead to the perception of this Absolute as a source of satisfaction, a feeling of well-being, and serenity.
