Ayya discusses three different contemplations on mortality.
1. Charnal ground meditation - visualizing the different stages of decomposition of a corpse.
2. Contemplating that death is inevitable. When it will come is uncertain. The place it will happen and it's cause are unpredictable. We have to give up everything when we die....our relationships, our status, our possessions. Every moment we come closer to our death. We hold these thoughts in our mind, feel the resistance and just sit with what arises.
3. On each in-breath, think, this could be my last breath. On each out-breath, relax.
Ayya gives a guided meditation on the third method.
