The specifics on how to meditate on impermanence according to Mipham Rinpoche’s teaching can be found in the discourse on the Four Dharma Seals in the book series Wisdom Light. There is also a clear explanation in the Theravada teachings on how to meditate on the impurity of the body. At the beginning, you may be unwilling and tend to resist these practices. But you must convince yourself to undertake these practices in order to take control of your own mind.
