Eckankar teaches that there is an audible life current known as the ECK, or Holy Spirit, that connects each of us with
the heart of God. We can experience the ECK as Light and Sound. Through study and practice of the Spiritual Exercises of ECK, we learn to recognize the Light and Sound of God as It touches our lives and brings increased divine love.
The Light and Sound are the Voice of God, the expression of God's love for us. They comprise the whole of God's love. Together, they are what religion calls the Holy Spirit.
