Your turbulent mind (ego) is like the waves on the ocean surface, always restless. But if you go deep under, it remains completely undisturbed even if a fierce hurricane is blowing above. Know that you are that infinite depth, not the agitated waves.
If you sit in a totally dark room, lighting a candle may bring great relief. Thus candle on = happiness and candle off = unhappiness, similar to life situations. Suddenly you discover that the room has shutters on all sides and you open all of them and light streams in (enlightenment!). After this, turning the candle on and off (life’s ups and downs) has only a minor effect on you.
If you're wondering - yes, my dad is the man :)
