Just as a weak person becomes healthier and stronger if they exercise more and more and is thereby able to exercise even more, a person who makes taking action upon their thoughts a habit will have even greater power to take action.
-Heaven's Words My Words-
If you want to pray deeply, concentrate and continuously call upon the Lord’s name.
Then, your heart and mind will gather together, which gradually makes distracting thoughts disappear.
If you call him at that moment, you will strongly feel that he is very near, looking at you.
If you continuously pray from this state, you will feel the Lord vividly and be able to converse with Him.
