You need nothing to be happy - you need something to be sad.
All experiences come and go. What witnesses experiencing itself?
You are here. You are not the one who will go and come. Let what you're suffering from go and come, not you. You stay put.
Let every thought come and hug you, but you don't hug anything. Then, gradually, the noise will start to back off.
Pay attention to that which sees the mind.
All the mind-streams eventually flow into the One ocean Beingness. There are many pathways for the mind; there are no paths for the Heart, for the Heart is infinite and fills everything.
