NOT BITING THE HOOK
'In Tibetan there is a word that points to the root cause of aggression, the root cause also of craving. It points to a familiar experience that is at the root of all conflict, all cruelty, oppression, and greed. The word is 'shenpa'.
The usual translation is 'attachment", but this doesn't adequately express the full meaning.
I think of shenpa as "getting hooked". Another definition, used by Dzigar Kongtrul Rinpoche, is the "charge"----the charge behind our thoughts, and words, and actions, the charge behind "like" and "don't like".
Here's an everyday example: Someone criticizes you. She criticizes your work or your appearance,
or your child. In moments like that, what is it you feel? It has a familiar taste, a familiar smell.
Once you begin to notice it, you feel this experience has been happening forever.
That sticky feeling is shenpa.
And it comes along with a very seductive urge to do something. Somebody says a harsh word and immediately you can feel a shift. There's a tightening that rapidly spirals into mentally blaming this person, or wanting revenge, or blaming yourself. Then you speak or act.
The charge behind the tightening, behind the urge, behind the story line or action is shenpa.
You can actually feel shenpa happening. It's a sensation that you can easily recognize.
Even a spot on your new sweater can take you there. Someone looks at us in a certain way,
or we hear a certain song or walk into a certain room and boom.
We're hooked. It's a quality of experience that's not easy to describe
but that everyone knows well.
Now, if you catch shenpa early enough, it's very workable. You can acknowledge that it's happening and abide with the experience of being triggered, the experience of urge,
the experience of wanting to move.
It's like experiencing the yearning to scratch an itch, and generally we find it irresistible.
Nevertheless, we can practice patience with that fidgety feeling and hold our seat."
