How does a mantra act scientifically? Every sound and form has a different archetype inside the brain. The process of knowledge takes place through these archetypes. As I am talking to you, knowledge simultaneously takes place inside you, but this process is not based on the actual sounds I am pronouncing. As soon as the sound goes into the brain, it changes its waves and assumes various geometrical patterns. These patterns are the archetypes. Now, in science, the principle is that perception and cognition take place inside through the intermediary archetypes, and what we perceive is not exactly as it was outside.
There are infinite archetypal patterns. In yog they are known as mandalas and yantras. Scientists have found that by producing certain sounds, certain flower-like shapes were formed. When certain mantras were chanted, they found that they created the archetype of a lotus flower.
Mantra has its own field by which it travels. In this universe, there are thousands of channels of waves. We call them layers or zones. In one layer radioactivity travels, in another layer electromagnetic waves, in the third layer thought waves.
When you produce a sound, it attains a certain frequency. If your mind is dissipated then the frequency is low. If your mind is one-pointed, then the frequency is high. Your mind is a part of the cosmic mind.
