So the whole conflict between mind and matter, and their followers, is baseless, because the ultimate substratum that physics has now come to know is really neither like matter nor like mind. The division has disappeared, the duality has disappeared. The behavior of the basic substance is very vague: sometimes it behaves like matter, and sometimes it behaves like mind. You may be surprised to know that physics cannot say anything about individual atoms – they are unpredictable, just like any human being. Nothing can be said about the individual atom and how it is going to behave. It appears that it has a certain independence; no causality can predict how it is going to behave. We can predict mass behavior, but we cannot predict the behavior of an individual atom. Sometimes it behaves in cause-effect terms, like matter, and sometimes it behaves like mind, as if it has a will of its own, as if it has a choice.
With Tantra, this idea of physics fits very well. But why does Tantra say that the basic reality is the third, the unknown, the “X”? Not because Tantra is interested in propounding any theory about reality, no. It is proposed just as a help for sadhana, just as a help for spiritual growth. If it is so – that the reality is the third, and mind and matter are just two manifestations – then you can enter the reality through two doors: either from matter or from mind. If you try to enter from matter, then there are certain techniques to use. Hatha Yoga is a technique to enter the reality through matter, through the body. You have to do something with the body, you have to transform the body, you have to crystallize certain chemical phenomena in the body, and then you will enter into the reality.
Or, you can enter directly through the mind. Raja Yoga and other methods are used to enter through the mind. And for Tantra, both are right.
You cannot say to Tantra, “How can a body posture, a particular body posture, be helpful to enter reality?” Tantra says it can be helpful. A certain body posture is not a mere body posture, because body is the manifestation of the reality. So when you give your body a certain posture, you are giving the reality a certain form. And there are postures with which you can easily enter into yourself. A certain food can be helpful. A certain practice of breathing can be helpful. These are material things – food, breathing, body. But you can enter through them.
And similar is the case with mind: just working with mind also you can enter. Many times the question may have arisen in your mind about Shiva telling Parvati certain techniques which look just imaginary. The question is bound to arise – how can imagination be helpful?
Even imagination is a mode of reality because the mind is a manifestation of reality. And when you change the imagination in the mind, you are changing the mode of reality. For Tantra nothing is unreal. Even a dream has its own reality – and it affects you. So a dream is not a mere dream. A dream is as real as anything else because it affects you, it changes you. You are different because you dreamed it; you will never be the same because a certain dream has happened. So if you dream that you are a thief, in the morning you will say that it makes no different, it was just a dream. But for Tantra it is not so. A dream of stealing, of theft, has changed you. Your reality is different in the morning; you cannot be the same. Whether you recognize it or not, it has affected you. It will affect your behavior, your future – it has become a seed.
