Thinking gives off smoke to prove the existence of fire. A mystic sits inside the burning. There are wonderful shapes in rising smoke that imagination loves to watch. But it's a mistake to leave the fire for that filmy sight. Stay here at the flame's core.
RumiThose who are pure in heart achieve God-consciousness; they are truly and actually aware of God at the center of their being (their heart). These sanctified individuals are said to be Possessors of the Heart.
RumiYour thoughts are a veil on the face of the Moon. That Moon is your heart, and those thoughts cover your heart. So let them go, just let them fall into the water.
Rumi
