That is true power. That is true freedom.

Swami Vivekananda was a direct disciple of Sri Ramakrishna and a fierce advocate of the path, specifically the mental science laid out by Patanjali. His core teaching regarding the power of mind can be summarized in one sentence:

Vivekananda taught that you only waste mental power through the senses. When you read the PDF, disconnect from Wi-Fi. Turn off notifications. This physical act of withdrawal is the first step of mental power.
