“If you just sit and observe, you will see how restless your mind is. If you try to calm it, it only makes it worse, but over time it does calm, and when it does, there’s room to hear more subtle things. You see so much more than you could see before. It’s a discipline; you have to practice it.”

additive-symbols

The additive-symbols descriptor lets you specify symbols when the value of a counter system descriptor is additive. The additive-symbols descriptor defines additive tuples, each of which is a pair containing a symbol and a non-negative integer weight. The additive system is used to construct sign-value numbering systems such as Roman numerals.
