How many sessions are in a meditation course?

That depends on the type you pick and how far you want to go. A Techniques course runs 3 sessions at Short, 5 to 7 at Standard and 10 to 14 at Deep. Loving-kindness runs 3, 6 or 8, moving through the traditional circles of metta one at a time. Goal-based runs 5, 8 or 12, because one intention needs room to be approached from several angles. Self-discovery runs 4, 6 or 8. You see the whole sequence, every session named, before you begin.
