Lightning Flash of Alef Volume 5: Quintessence of Secret Mercury 
Quintessence of Secret Mercury has three sections. The first describes the five aspects of a mental construct imbued with life force, known as a golem. In mystical contemplation, any mental construct can serve as a sacrificial offering to the essentiality that animates it, thereby forming a self-perpetuating sacrificial stream. The second section is a serial narrative of sixteen images called Tikkun of the Circle that comprises a mutus liber (wordless book). The third section presents a very special text (bearing the name of this volume) written in retreat over a ten-year period. It presents many of the major symbolic themes that are expressed in all seven volumes of the Lightning Flash of Alef series.
