My experience is that devotees, who attend the MI Bhakti-sastri Course, become competent preachers of our Krishna conscious philosophy. Many are establishing centers and conducting seminars without assistance from others.
In Taiwan for example, one householder couple, who took the course, now have their own center in a large city in southern Taiwan. They are recognized by the local people as authorities on the science of yoga, and are, therefore, regularly asked to give lectures to yoga teachers and their students. They both feel confident to handle preaching engagements on their own although they get only limited association with senior devotees. They are full of appreciation for the training they received at the MI.
We also had several Chinese devotees with good English skills take the course, and, upon their return, were able to translate the Bhakti-sastri materials into Chinese and are now offering the course to Chinese devotees.
