The third mouth eats smells. The fourth mouth eats tastes. The fifth mouth eats physical contact. And the last mouth eats ideas. That is feeling.
Time is also an eater.
In traditional Cambodian stories, there is often a giant with many mouths who eats everything. This giant is time. If you eat time, you gain nirvana. You can eat time by living in the moment. When you live just in this moment, time cannot eat you.
