What do you want to know about it? It is a perfect representation of the microcosm and the macrocosm. It is one of the most ancient sacred geometry yantras ever known to mankind.
It consists of nine Avaranas (veils, walls, enclosures) - which separate one from realizing the full potential of the Self as the Divine. The center is Tripurasundari, the Goddess of the Triads (also a combined form of the child, maiden, and the crone), who represents the transcendental sixteenth digit of the waxing/waning of moon - which represents the transcendence of space and time, two aspects which prevent us from realizing our own true Self as The Goddess.
The nine enclosures and the tenth Bindu (the central dot where all the nine enclosures collapse) is the state of singular, non-dual Divine Consciousness where the Deity and the Practitioner are One.
For material benefits, one worships/meditates on the Srichakra from the center, outwards - like the rays of sun emanating outside from the center. For spiritual ascent, we meditate in the reverse order, from the outermost enclosure to the innermost - where each gross layer of consciousness collapses into the more subtle one, till the mind becomes no-mind. Each enclosure has its own set of deities with specific internal and external purposes. For example, one of the enclosures is called Sarvarogahara - that which cures all diseases, another called Sarvarakshakara - that which protects from all physical, mental, and spiritual dangers.
The Alchemy of Srichakra is extremely complex and involved and a whole school in itself called Srividya. This is a very ancient (and extremely extremely powerful) Tantric school that combines Yoga, Tantra, Alchemy, etc. in itself. It involves Mantra (of three, six, nine, fifteen, sixteen, and twenty-eight letters, given in sequence after the previous one if perfected), Mudra (forty-eight hand gestures), Tantra (ritualistic invocation, internal meditations of six kinds in the subtle energy body). Initial work is physical, and then mental and finally astral where one traverses through a Srichakra constructed in the astral body. At an advanced state, we traverse through an actual dimension dedicated to this alchemy in astral body to the levels permitted by the guardian deities (which depends on our vibratory state, the work we have put in).
This Mandala or Yantra represents the harmony of Shiva and Shakti in conjugal bliss - upward triangles are Shiva, downward ones is Shakti, as their coming together results in the apparently real universe. The Bindu represents the state of pure ‘I AM’, as all that there is. The nine enclosures also represent the nine Chakras, nine dimensions/worlds and nine states of consciousness.
