A German scholar was preparing to leave for India to learn yoga. His colleagues asked him if he was going there to learn the yoga siddhis, or mystic powers. The scholar replied that he was not. He said that the yoga siddhis or mystic perfections were already being duplicated by modern science and he was therefore not interested in them.
He told them, "The mystic yogi struggles for decades to achieve the power to levitate or the power to stay underwater for long periods of time. But with the development of airplanes and submarines, modern scientists have achieved the same aim."
"Then what kind of yoga are you planning to learn?" they asked him.
"I am going to learn the process of yoga that leads to the perfection of spiritual love. That is the true and highest goal of yoga."
