The quantum physics has reached this amazing result: in nature, there is a degree of incertitude involved in each process.

From Newton and Descartes, most of the scientific community and almost the whole of the Western society embarked on the hypothesis that the evolution of each system (including man) is completely determined, step by step by its previous state.

Thus, the conclusion that one may precisely determine the future if perfectly acquainted with the past emerged.

In other words, if we were to program a powerful computer with all the data it requires, we may even simulate perfectly the evolution of the universe in general, and of the human being in particular.

However, in the end this assumption is quite a big mistake. The recent discoveries in modern physics did not validate the concept of “determinism”.

They proved that certain phenomena, connected with the quantum level of reality can not by predicted. They are the so-called “incalculables”. Each quantum phenomena includes a degree of freedom.

Each time the wave function collapses, the result has a chance degree.
This may be associated with the free will, which is non-deterministic.

The particle may reach a final state that does not depend on its past. In other words, a “free choice” is allowed.

Heisenberg’s principle explains this degree of freedom. He proved that nobody could perfectly accurately observe a particle. We either know precisely its position, but not its trajectory, or we know precisely and accurately its trajectory, but we do not know its position.

This limit in observation induces an intrinsic degree of incertitude, an imprecision at a theoretical level, a degree of indetermination in each act of observation.

Modern physics allows the concept of free will even at the most fundamental level, contrasting to the deterministic theory of Newton and Descartes, which consider that faith is decided from the start, and in an inexorable manner.

This change of heart reinstates the free will, that is – the possibility of each human being of influencing one’s own faith and not be subject to a blind destiny.

This view of free will has always been a part of the Tantric philosophy. The Tantric practitioner accepts the idea of karma, but he also considers that the evil that has not yet become manifested can and should be removed.

According to the Tantric philosophy, the degree of spiritual evolution of a human being is directly proportional with the degree of freedom that being has. At the ultimate level, God is defined as SVATANTRIA – supreme, absolute freedom, free from any constraint.

The degree of freedom of a certain person is quite relevant to what his/her spiritual evolution is concerned.

For instance, a person who tends to be subject to all kinds of social dogmas, without thinking them over first, who is ready to take over already “thought” ideas without filtering through his/her own mind shows a reduced degree of inner freedom.

Spiritual freedom is in tight connection with the concept of free will. Spiritual freedom is not related to not being imprisoned in a cell, but to being capable to think for oneself, without any limitations.

Being free from mental and psychic chains is much more important than exterior freedom.
