The mind is naturally spacious.

It can hold anything – joy, sorrow, fear, excitement—without being destroyed or overwhelmed. The trouble begins when we forget this capacity and start to believe that our thoughts and emotions are solid, permanent, or bigger than the mind itself. We contract around them, tightening our mental grip, as if holding on could somehow make life more secure. But the truth is, the mind is like the sky—vast, open, and inherently calm. Clouds (thoughts, worries, pleasures) pass through, but the sky remains unchanged.

Meditation is the practice of remembering this.…This spaciousness isn’t something we need to create; it’s already here. Our practice is to recognize it. When we do, life becomes lighter. Difficult emotions don’t disappear, but they no longer define us.
