the detailed instructions for the insight practices are what make mahāmudrā (and dzogchen) unique in tibetan buddhism. in mahāmudrā vipaśyanā, wangchuck dorje gives ten separate contemplations that are used to disclose the essential mind within; five practices of "looking at" and five of "pointing out" the nature of mind. they all presume some level of stillness cultivated by mahāmudrā shamatha. in retreat, each contemplation would typically be assigned specific time periods.
