The word Yoga is derived from the Sanskrit root *Yuj*, which has two important derivations given by ancient grammarians. The first is *Yujir Yoge*, meaning "to unite" or "to join," and the second is *Yuj Samadhau*, meaning "to concentrate" or "to attain deep meditative absorption." Thus, Yoga signifies both the union of the individual self with the universal consciousness and the disciplined process of achieving complete mental concentration. It is a comprehensive system that harmonizes the body, mind, intellect, and spirit, enabling a person to attain physical well-being, mental balance, ethical living, and spiritual liberation. The meaning of Yoga extends beyond physical postures or exercises. It is a philosophy, a science, and a practical discipline that guides individuals toward self-realization. Yoga aims to remove ignorance, suffering, and mental disturbances while cultivating self-awareness, inner peace, and harmony with nature. It encompasses moral conduct, self-discipline, breath regulation, meditation, and wisdom. Different classical texts define Yoga according to their philosophical perspectives, but all emphasize self-mastery and liberation. One of the most authoritative definitions is found in Patanjali's *Yoga Sutra*, where Yoga is defined as *"Yogah Chitta Vritti Nirodhah"* (Yoga Sutra 1.2), meaning "Yoga is the cessation of the modifications or fluctuations of the mind." According to Patanjali, the restless mind is the cause of suffering and ignorance. When mental distractions are controlled through systematic practice and detachment, the true nature of the self is realized. This definition forms the foundation of Classical Yoga and highlights mental discipline as the essence of Yoga. The *Bhagavad Gita* presents Yoga in multiple dimensions. Lord Krishna defines Yoga as *"Samatvam Yoga Uchyate"*
