"Arhat" is a ancient Buddhist term for spiritually Advanced Being, a Paramahansa, or what the western layman would call a Saint.

Arhatic Yoga is thus composed of the teachings, the techniques and procedures for becoming an Arhat. In ancient times, these teachings were given only to a mere handful of students, who were very much dedicated to the practice of the teachings, but were also sworn to the utmost secrecy. Thus, not much can be found in books about this type of Yoga. However, we have heard stories from ancient times to the present of individuals unique enough to have attained a relatively high degree of spirituality. They have manifested this either through successfully healing ailments in a miraculous way, and/or by propounding and promoting spiritual teachings for improvement of everyone's lives.

These beings were in all probability either Arhats-in-the-making, real Arhats, or may be even beings who have transcended the Arhat stage. How these beings have developed spiritually, their techniques and practices, have not been often clearly spelled out. Stories say some of these Saints, or Arhats were already born with a high degree of spirituality, while the others 'meditated' extensively throughout their lives. But still not much is known about the specific techniques and practices for Arhatship. In all probability, it was because of the potency and power of these teachings, that they were kept secret, and exclusively reserved only for the highly educated during those ancient times - the royalty and/or the high priests. But in these modern times, with the progress of Humanity and the advancement in Humankind's consciousness, more and more people are ready and prepared to embark on the Path to Arhatship. It is this present condition of the human race that has encouraged the revelation and presentation of Arhatic Yoga to the public, through the Institute for Inner Studies Inc, and its Founder, Master Choa Kok Sui.
