Let him be foolish and troubled for a long time, and his heart will be civilized and sweet.
Your dream is so real that it shows what you usually want, and that desire will naturally be reflected in your dream. Simply put, what you see is what you know.
According to Buddhist theory, what all beings see from the outside is illusory, and the images in dreams are illusions. All kinds of dreams represent your inner hesitation and struggle. Maybe the unpleasant things in your life have disturbed your mood recently. The "dream person" is actually your inner "false self", that is, "obstacle". These phenomena are called "magic from the heart". As long as you don't cling to fantasy, your "true self" will emerge, which is what Zen says, "seeing your heart clearly"! Think of everything, think of everything! Only by eliminating delusions can wisdom appear and troubles be removed!
The Heart Sutra says, "There is no obstacle in your heart, no fear, stay away from upside-down dreams, and eventually nirvana." As long as you can realize it from your dreams, you can show your wisdom and get rid of your troubles!
Happiness and pain are from the heart, and the troubles in the world are all caused by themselves. As long as you don't cling to fantasy, give up ignorance and dreams, your mind will be rich and your mood will be happy!
Yesterday was just a lost dream, and tomorrow is an elusive illusion. Only grasping the present is the truest!
