The third type of instruction explains how to block rebirth if one fails to become awakened using the second set of instructions. At this stage, the person to be reborn sees their future parents having sex and feel attraction towards the father or the mother (depending on their sex). Then they will enter the womb and into a new rebirth. However, the deceased person can prevent this process by staying calm and entering meditative absorption when they have the vision. They can image their parents as lamas or as deities if this helps avoid feelings of desire for them. They can also contemplate that they are empty, like illusions and meditate on radiance and emptiness.
