In Allah's Boundless Love
Envision your heart as the Kaaba, or envision your heart as the Black Stone embedded within the Kaaba. The Black Stone is reported to be the stone of witness in pre-eternity, upon which every soul witnessed its primordial 'Yes!' to Allah when Allah asked all the souls "Am I not your Lord and Lover forever?"
Envision the angels circling round your heart chanting praises to Allah.
Envision the hand of Rasulallah, may he be immersed in Allah's peace, under your heart, supporting it.
Envision Allah the Beloved gazing at your heart.
Envision your heart gazing back and becoming flooded in the pure light of perfect Love, "Blazing, blissful unity of pure Being"
