Why art thou cast down, O my soul? and why art thou disquieted in me? hope thou in God: for I shall yet praise him for the help of his countenance. Psalms 42:5 KJV
Have you realized that most of your unhappiness in life is due to the fact that you are listening to yourself instead of talking to yourself?
An undisciplined mind will keep the problems of yesterday and the worries of tomorrow in the place that robs you of your present.
Instead of allowing this, start talking to yourself. “Why art thou cast down, O my soul?” The writers soul had been depressing him, crushing him. So he says, “Self, listen for a moment, I will speak to you. My hope is in the Lord and I will yet praise Him". You have permission to talk to yourself. Sometimes the mountain that needs to be removed, is the mountain of imagination in our mind. Speak to it.
