The practice of yidam

The word 'yidam' can be translated as 'awareness-being' or 'meditational deity'.   To arise as the awareness-being, is to wear the body of visions.  The form of the yidam gives us the opportunity to enter the world of form as the yidam.  This is what is called living the view.  Living the view means that we retain the feeling that we are the yidam in whatever we do.  We experience the world around us as the realised dimension of the yidam.

Overt nonsense

     If you’re able to let go of reference points to the extent of identifying completely with the awareness-being; you would be able to observe yourself for an instant as the awareness-being would view you.  You would gain some glimpse of your dualistic structures as being monumentally absurd.
Catching yourself in the act of confusing yourself with the more overt nonsense patterns of samsara, is going to change your relationship of involvement with those patterns.  The patterns would have a transparence in the afterglow of wearing the body of visions that would make it difficult, though not impossible, to take those habitual tendencies completely seriously.

Emptiness is the oven where the bread of vision bakes itself

  After you've received empowerment into the practice of a particular awareness-being, or yidam, the form of this awareness-being will spontaneously arise out of the state of emptiness when you engage in practice.  The form of the awareness-being will also arise in your dreams – maybe even in the steam that arises from your cup of coffee.  It depends on the intensity of your devotion.  There is no process – it simply happens because you have the key; and the key is the Tantric text or the awareness-spell which is sung to instigate this arising.  Your experience of emptiness is the oven where the bread of your vision bakes itself.  The empty state is the perfect environment for endless vision to arise.
