Today everybody knows what yoga is but their understanding is generally limited to physical postures, known as Asanas. But Does yoga implies physical poses? To discover the appropriate answer, we need to understand the meaning of yoga in the ancient writings.
Yoga is a word from Sanskrit language which means join. When 2 or more objects are joined, then it becomes one object. There is connection and association between 2 objects which have become one. So yoga is about unity, experience of unity, feeling of harmony.
