Breathing
We must master our inspiration (Puraka) and expiration (Rechaka), as these rates are a reflection of our mental state. Every time we breathe in we have to realize that life is entering into us, as to hold your breath with full lungs and expand it represents life in the body, diffusing it, perceive it in its entirety. The expiration, however, is associated with sadness and abandonment, a symbolic death, which is why whenever we become aware that exhale the breath of life out and away from us.
Abstraction or Pratyahara
It is “isolate the senses”, to escape all that is external, any material form. That feeling, which produces rid of everything that surrounds us is an experience, but is not readily available. You can only achieve by being faithful to exercise and very consistent.
Concentration
Develop a strong concentration is similar to the development of physical strength. The goal is to help control the mind to concentrate on a particular item, either an object or a sunset.
Visualization
Seeing with the mind, is what we do in the transition between concentration and meditation is this intermediate stage through which we create images in our mind, we envision a situation that makes them stop our mental rhythms.
Meditation
It is the goal that we looked at the outset, we have inside. Only from this nothing can begin a genuine process of knowledge.
