Luke 17: 21 The Kingdom of God is within you. It grows on the inside of by renewing your mind into the Mind of Christ.  And it becomes a river of living water overflowing from within you, and you will feel the presence of the God Almighty, and he will never leave you. 

I call it Heaven Awareness. 

John 3:5 Except a man is born of water and of the Spirit, he could not enter the Kingdom of God

The water is spiritual which is the Bible  the word of God, and the Holy Spirit within you.

Born from spiritual truth knowledge taught by the Holy Spirit.
