The wheel of emotions

"Emotions are the silt1 of the soul".

1 The different meanings of the word silt:
Meaning 1: Very fertile soil.
Meaning 2: Botanical: lemon
Meaning 3: Stretcher used to harness a horse
Meaning 4: Part of a staircase that supports the handrail.

We move through life with silt... Emotions irrigate the fertile soil of our souls and nourish our bodies. So why the lemon analogy ? Emotions are fabulous engines for progress. In fact, doesn't e-motion mean movement? Emotions can also sting the eyes when events are painful. In such cases, we'd like a carriage to help us up the slope .
