This quote indicates the speaker has attained a state of tranquility from within. They seem to have discovered an inner calm and equilibrium that provides a retreat from external noise and chaos. The peace arises from their own being rather than outside forces.
By using the phrase "I have found," the quote suggests this peace was revealed through introspection and self-work. It was not bestowed upon them but unearthed from their own inner reserves. The speaker tapped into an inner vault of stillness, patience and insight.
The quote serves as inspiration that we all can find an oasis of calm at our core. By looking within, through spiritual practices and self-reflection, we can become grounded in presence and being. True peace is not contingent on others or external conditions. Like the speaker, we need only journey within to realize the wholeness already residing inside us.
