If it is a group with practitioners that are more conversant with Bhakti culture/philosophy, the program flow can look something like this:
-Ice Breaker/Meet & Greet
-Short Kirtan
-Read BG or SB verses and discuss (with a steady group this might be done in chronological order, so the group finishes chapters and possibly Cantos together)
-Light Prasadam and an opportunity for individual heart-to-hearts.
If the audience is newer, then a similar format can be followed but instead of taking turns reading verses there can be a selection of topics that are discussed.
Of course. reading verses might also be good for a newer crowd but your team can decide that.
