By mental cultivation I mean a disciplined application of mind that involves deepening our familiarity with a chosen object or theme. Here I am thinking of the Sanskrit term bhavana, which connotes "cultivation," and whose Tibetan equivalent, gom, has the connotation of "familiarization." These two terms, often translated into English as meditation, refer to a whole range of mental practices and not just, as many suppose, to simple methods of relaxation. The original terms imply a process of cultivating familiarity with something, whether it is a habit, a way of seeing, or a way of being.
