A skull cup symbolizes cutting through the identification with our body and its endless wants and needs by remembering death – impermanence.
During tantric rituals, one offers one’s hatred and greed and transforms them by ‘cooking’ them in the skull cup which transforms them into nectar with the help of the meditational deities who add their blessings.
This nectar in turn is offered to all sentient beings as all the food, medicine and worldly and spiritual help they need.
