meditation, in reality, is a state of discipline, where you detach your mind to reach that stage where you are observing in alertness with all awareness but without thinking. When the consciousness in a man detaches itself from the objects which mind perceives, this state is referred to as 'thoughtless awareness'
There are three basic aspects of meditation. The first is the spiritual revival for any person to connect to the infinite, the eternal spirit of oneness or the real Self. The second is to submerge your mind into deep concentration through chanting, mantras and various methods in breathing for a specified defined reason. The third is living in meditation with mindfulness in thoughtless awareness with full acceptance to transform.
In mindful meditation you do not concentrate or contemplate, you do not practice; it is your basic nature.
When thoughts end, meditation begins. When you just watch your mind without thinking in observance and alertness, you become aware. You become a witness to your own mind; watching and witnessing. Meditation in such awareness, takes you inwards into the subject. It is the luminous awareness of the Self. It takes you away from your "me and mine" from your desirous self, into what you are in silence. Where there are no words, language, logic or reasoning.
Just you as you are; reminding you that you are not your physical identity, name, religion or nationality, but the consciousness in continuity. Meditation is not for five, ten or fifteen minutes, like in Transcendental Meditation, which being more of therapy. It is to get away from the past and the future to live in the now, from one moment to the next. To be alive and not to repeat any words, mantra, name of God or focus into anything.
Meditation, in this case, is to live in the spontaneous now, without any interference from the thoughts of duality. It is the process of centering your energies into that oneness to which we belong.
