Quote

Rumi·1250

Everyone sees the unseen in proportion to the clarity of his heart, and that depends upon how much he has polished it. Whoever has polished it more sees more — more unseen forms become manifest to him.

Marcus Aurelius·180 AD

Nowhere you can go is more peaceful — more free of interruptions — than your own soul.

Seneca·63 AD

The primary indication, to my thinking, of a well-ordered mind is a man's ability to remain in one place and linger in his own company.
