Our final goal is to produce a very strong and precise feeling of emptiness or impermanence each time we meditate. When not meditating, our temporary objective is to be able to experience emptiness and impermanence naturally without having to think specifically about these concepts in everyday life.

Originally, at the time the precious stones were extracted, they were covered with dirt and sand, and did not glow. The people who extracted them first placed them in a chemical solution to loosen the contaminants, then used a very rough piece of cloth to clear the dirt and sand; next they placed the stones in a finer solution and used a more delicate piece of cloth to clean them; finally they used silk to polish them until they were crystal clear—at that point the precious stones would light up.
This analogy tells us: during the first turning of the wheel of Dharma, sentient beings who came were of relatively low capacity; accordingly, the teachings focused on impermanence and suffering in the Four Noble Truths to help beings eliminate self-attachment and afflictions, namely desire, anger, and delusion, at the gross levels of mind. This is likened to the first stage of processing the precious stones.

Offering of Dharma is particularly important. If we are given two choices: 1) we can release all the fish in the market free of charge on condition that we do not recite the Buddha’s names for them or feed them nectar pills; 2) we can recite mantras, feed them nectar pills and bless them with the text of ‘liberation upon wearing,’ but we cannot buy them to set them free. Which one should we choose? Make sure it is the latter.

The practice of impermanence is of two kinds: one is impermanence at the microscopic level; the other is impermanence at the macroscopic level. In The Words of My Perfect Teacher, the discussion on impermanence is entirely at the macroscopic level; in general, not much is said about impermanence at the microscopic level. However, both types shall be discussed here.
