Many Sages have said, "Your world is a dream. You're living in an illusion." They're referring to this world of the mind and the way we believe our thoughts about reality. When we see the world through our thoughts, we stop experiencing life as it really is and others as they really are.
Whenever you aren’t manipulating your experience, you’re meditating. As soon as you meditate because you think you should, you’re controlling your experience again, and you’ve squeezed all the value out of your meditation.
You can't lose what you serve. That's the secret. What you serve, you can't lose. What you don't serve and what you try to hold onto, you can't hold onto. It's always slipping out of your fingers.
