IS IT IMPORTANT TO PRACTICE THE KHECHARI KRIYA MUDRA?

Yes, it is a very important practice... I was first taught Kechari Mudra as a boy by disciples of Totapuri, the Vedanta Guru of Shri Ramakrishna... The real meaning of khechari is kha, meaning: “in the vacuum,” and chari means “to fly” or “to roam freely.” If you can go from the lower chakras to the higher chakras, that is, above the neck center, then you are in Khechari Mudra because the vacuum begins from the neck and there are five layers of vacuum from the neck and above at the spiritual eye up to the Sahasrara... One who always is in the Self "Atman" is practicing the authentic khechari...
