Science is most commonly defined as the investigation or study of nature through observation and reasoning, aimed at finding out the truth. The term science also refers to the organized body of knowledge humans have gained by such research.
Since the yogic approach to spirituality uses both observation and reasoning to get at the inner truth, it must, therefore, be a science.
Meditation has been described as intuitional science. Extensive laboratory tests have demonstrated the physiological effects of meditation, but this only shows us its external effects. Even a recording of a person’s brainwave patterns is just a measurement of physical electrical waves. It does not tell us exactly what they are thinking or feeling. The only real laboratory for testing meditation is the mind itself, and the results need to be experienced personally. Another name for this science is Tantra – the science of spiritual meditation, which enables the practitioner to merge his or her unit mind into Infinite Consciousness.
