Learned Audience, it has been the tradition of our school to take 'Idealessness' as our object, 'Non-objectivity' as our basis, and 'Non-attachment' as our fundamental principle. 'Idea-lessness' means not to be carried away by any particular idea in the exercise of the mental faculty. 'Non-objectivity' means not to be absorbed by objects when in contact with objects. 'Nonattachment' is the characteristic of our Essence of Mind.
