In the 19th and 20th centuries there was the Renaissance of Yoga in India. This was the basis upon which from the 60s yoga has spread more and more throughout the world.
Names like Ramakrishna, Vivekananda, Shri Aurobindo, Ramana Maharshi, Anandamayi Ma are like shining stars in the sky.
Swami Sivananda stands out in my opinion: It was especially convenient. He made the practical aspects of yoga popular. Hatha Yoga, Meditation, Mantra - Swami Sivananda concern was that practicing yoga aspirants. And this practice motivated and motivated Yoga practitioner to yoga to become teachers - and gives them power to spread yoga.
