Heart problem.

When the eyes of the heart open, we can see the inner realities hidden behind the outer forms of the world. When the ears of the heart open, we can hear what is hidden behind the words; we can hear the truth.
Opening the heart means coming closer to God. God said, through Muhammad, “I who cannot be fit into universes upon universes, fit into the heart of the sincere believer.” The heart is a temple that can house God. To open our hearts is to allow in the divine presence.
The heart of hearts in each of us houses a spark of the Divine. This is the meaning of the biblical and Koranic quote, “And God breathed the breath of life into Adam,” also translated, “And God breathed divine spirit into Adam” As our hearts open, we come more in touch with the wisdom, love, joy, and inspiration from the divine spark within.
All wisdom is already within us; all love is already within us, all joy. Yet they are hidden within us until the heart opens.
I would like help with my heart problem. I have diagrams of the heart. I know the direction the blood is pumped, some of the control mechanisms and have seen open heart operations. The problem is, that although I understand the above passage from ‘Essential Sufism’ Chap 9, the image of ‘heart’ gives me biological images and as a metaphor it’s not quite working for me.
