When there is no thought. no desire, no ambition, in that state of no-mind truth descends in you - or ascends in you. As far as the dimension of truth is concerned both are the same, because in the world of the innermost subjectivity height and depth mean the same. It is one dimension: the vertical dimension. Mind moves horizontally, no-mind exists vertically. The moment the mind ceases to function - that's what meditation is all about: cessation of the mind, total cessation of the mind - your consciousness becomes vertical; depth and height are yours.
