It means to link, to culminate or to agree. It is the culmination of body and mind or the culmination of Jiva and Shiva (soul and the universal soul). It's also a culmination of Purush and Prakriti (Yin and Yang).
Asana means obtaining a body posture and keeping it as long as one's body allows. Asana, when performed rightly according to the principles discussed above, render enormous physical and mental advantages. Asana is regarded as the preliminary step to Pranayama.
Practicing Pranayama is one of those ways of eliminating psychological disturbances and physical ill health. Pranayama means controlled and prolonged period of breath. Prana means breath. Additionally, it means life force. Ayama means controlling or elongation.
The same as a pendulum requires twice long to return to its first position, the exhalations in Pranayama are twice longer than the inhalations. The major goal of Pranayama is to bring mental stability and control needs by controlling breathing. Breathing is a part of an autonomous nervous system.
By bringing the involuntary process of breathing under control of mind, the range of volition is broadened. Pranayama is a bridge between Bahiranga (exoteric) Yoga and Antaranga (introspective or esoteric) Yoga. A body that is now stable by Asana and continues to be cleansed by Kriya (cleansing procedures) is prepared for Pranayama.
