Maitriasanga.  Love without obstruction.Or love without limits or love without materiality,concreteness that obstructs .

Actually there is sanga and asanga.Sanga is limit,asanga is without limit,or impediments.

So why Sanga? you put limits,cause you start to control yourself on the gross body,speach an mind level.

Than slowly you progress on major forms of control more subtle and just contemplating the clean clear nature of your mind you ……..THAT’S IT.
