In the Kalachakra system, (1) one who becomes a Buddha by first of all starting to stack up the first of 21,600 subtle energy-drops in the central channel. The term does not refer to a historical first Buddha, since Buddhism asserts there have always been Buddhas, with no beginning. (2) The subtlest level of each individual’s mental continuum, the clear light level, which has no beginning and no end. Its Buddha-nature qualities that allow it to become the omniscient mind of a Buddha include its innate purity from all fleeting stains and its innate quality or potential of unimpeded deep awareness. Thus, it is primordially a Buddha.
