Tantra is a technique that combines movement, breath, meditation and sound to assist in understanding consciousness.
Science does not belong to any race or religion, similarly Tantra is a Science and it is universal to all.
These meditation techniques may look simple and it is simple. We will just need simple but scientific techniques to achieve Higher Consciousness.
In Tantra doing is knowing and there is no other knowing. Tantra will not give you the answer, it will give you the technique to attain the answer.
No belief system is required. What is needed is a commitment and courage to experiment with the techniques.
