Phases of Meditation
Asana: Asana is the posture of the physical body. There are different postures for the practice of meditation, for example, the five-pointed star posture, the dead man posture, lotus posture, semi-lotus, siddhasana or perfect posture (which consists of closing the thumb with the index finger like a magnetic circle, resting the back of the hand on the knee); vajrasana or diamond posture (as the Inca and Japanese sit, with the hands supported on the thighs and with the trunk of the body resting on the heels), etc. The important thing, regardless of the asana or posture that one has adopted, is to keep the spinal column straight.
Pranayama: The science of the control of breathing. Prana is the sum total of the energy manifested in the universe. It is the vital force. Prana is the sum total of the latent forces hidden in the human being and that which surrounds him everywhere. Heat, light, electricity, magnetism, are all manifestations of prana. Prana is related to the mind. The place of prana is the heart. The breathing exercise is, therefore, one of the best paths that lead to concentration-meditation.
Pratyahara: Abstraction of the senses. The no-desire of the mind in meditation.
Dhyana: Meditation. In this state, the consciousness has the ability to know in any direction.
Samadhi: The consciousness is dissolved like a drop of water in the midst of the Great Ocean of Life, free in its movement.
