Classical or Isha hatha yoga denotes the most suitable form of yoga for today's world. The classical word is deliberately used here to represent the need of the time, which is coming directly from the source, Shiva without any mix, in its purest form. Classical hatha yoga is a science of understanding the mechanism of human structure and having the potential to reach the ultimate. It is Sadhguru's dream to have a drop of spirituality in everyone's life. The root or fundamental of yoga should reach every individual in its purest form, and in this, Isha Hatha yoga and Isha Hatha teachers are playing a very important role.
