Put sumeru in mustard seed and hide the sun and the moon in a pot.

It is a concept in Buddhism, which expresses the infinite possibility and relativity of the universe.

The two sentences "hide sumeru in mustard seed" and "hide the sun and the moon in a pot" have the same philosophical connotation. They all use examples from daily life to describe the elusive Buddhist thought.

As a symbol of Buddhism, "content with mustard seed" means that the micro world can contain the macro world. In Buddhism, Mount Sumi is the center of the universe, and mustard seed is the smallest unit, which is in sharp contrast. This metaphor expresses the truth that even small things can contain the universe.

"Hiding the sun and the moon in a pot" is another Buddhist symbol. The pot symbolizes the micro world here, while the sun and the moon are the representatives of the macro world. This metaphor expresses that even seemingly insignificant things may contain great energy and significance.

These metaphors reveal a core idea of Buddhism: everything is possible, all sizes, strengths and weaknesses, the rich and the poor are relative, and nothing is absolute. This is also the essence of emptiness or impermanence in Buddhism.

At the same time, it also implies an attitude towards life: seemingly small or insignificant things may also contain important truth or value, so we should keep a modest and open mind to explore and understand everything in the world.
