When you travel in an airplane, you can see all sorts of landscapes below — lakes, mountains, lush forests, deserts, cold and warm places. Likewise, during meditation, experiences of all kinds pass before your mind’s eye. At that time, the most important thing is to avoid any kind of clinging.
Don’t proudly think that these are “good” experiences and “Now I have realized the Great Perfection!” Neither should you be discouraged by “bad” periods of practice and feel like giving up meditation altogether, telling yourself, “I’ll never succeed.”
Let the mind remain in its completely natural, uncontrived state. Be like a newborn baby in its cradle. Even if surrounded by threatening armies wielding swords, the baby has no fear. In brief, there should be no modification of the natural state.
