The purpose of apprenticeship is to taste a unique depth of experience and involvement in a Vajrayana tradition without taking lifelong commitments. You can leap, but with the lifebelt of your probationary apprentice status. ….
You cannot know whether you are going to really like a cake unless you taste it. If you look at it and feel uncertain, or smell it and think that it doesn’t seem so good, but never actually taste it – you will never know what it tastes like. Vajrayana has to be tasted. So we would encourage you to use the probationary period to taste Vajrayana through this Lineage as thoroughly as possible. Taste with an open heart and an open mind.
