Scientists experiment in their laboratories with patient perseverance to find the truth. They don’t assert their theories unless they have positive proof. Likewise, India’s masters concentrated for years and years to solve the problem of how to live life properly. I am bringing to you the knowledge of mind and matter from the spiritual laboratories of India, as well as from my own experience. - Paramahansa Yogananda.

What is most important is to have a way to prove truth by our own Self-realization. We should not believe a thing just because somebody has said it… All truth must be tested and experienced by the scientific application of material, mental, and spiritual laws. - Paramahansa Yogananda.

Since ancient times, religious experiments have given India’s yogis knowledge of truths only now being “discovered” in the West by pragmatic scientific research. There is a definite need today for scientific religious experimentation applying the yogic methods of India. - Paramahansa Yogananda.

Religion should be treated as a science; it is right that it be subjected to the test of experience. - Paramahansa Yogananda.

In ages past, the rishis and masters of India, secluded in their hermitages, unraveled the mysteries that hide the Omnipresent Spirit. Their research has given us the valuable techniques and methods that tune the body and mind to the Illimitable Source of life and intelligence residing in every human being. By concentrating within on the Infinite, you can receive this boundless power. - Paramahansa Yogananda.
