Science is the systematic study of the structure and behavior of the physical and natural world through observation and experiment. Tantra is also an systematic approach of understanding inner and outer psyche both. It is also an holistic approach which approaches to the study of universe from the point of view of an individual. Various branches of sciences are drawn within it like astronomy, astrology, physics, chemistry, Ayurveda, Psychology, geometry and mathematics providing practical means of realizing highest ideals of philosophy in daily life.
Such sciences play a role in Tantra at various levels like Ayurveda is closely linked to Tantra and Ayurveda makes use of preparations made of alchemical forms of mercury, mica and other minerals. Such preparations are also an part of Tantra in which Ayurvedic preparations are used for mental and physical health.

Like Science in which we have defined theories and methods, Tantra is also a system of defined techniques. Science is not based on opinions or beliefs, it is the experience that matters. As in Tantra the practices are experiential, it is not the belief that generates results, but wisdom is a direct gain from practices. Tantra practices grows from gross to subtle giving us experience of each level of existence thereby transcending it.
The energy concepts of Tantra are now being recognized by many modern scientists. A strong similarity is being discovered between the scientific and tantric concepts of energy. The alchemical traditions found in China, Middle East and Europe have been linked to Tantra. In last century many scientists have described parallels between quantum physics and mystical view of reality described in ancient texts of Tantra.
Tantra also means “Technique” and it suggests that if the path is followed in a certain and defined manner the result is to be seen. Tantra is the most ancient experiential science, which takes us towards evolutionary existence, recognizing the complete human potentials. It is spiritual path that flourishes on every level of existence. The very scientific approach in Tantra gives it authenticity.
