All that you are attached to, all that you love, all that you know, someday will be gone. Knowing this, and that the world is your mind which you create, play in, and suffer from, is known as discrimination. Discriminate between the Real and the Unreal, the known is unreal and will come and go so stay with the Unknown, the Unchanging, the Truth.
