Ambarsaria Ji,

Interesting note: in one of Giani Maskeen Ji's katha's he mentions that there is some reference to Sassi Punnu in Gurbani and its actually APPROVED to be sung as keertan... (I'll have to dig and find that katha, unless you already know of the reference) just b/c the love between the two of them was so exalted, so divine... akin to the love one should feel towards God.
