When you first learn about mandalas, you learn about [sand paintings](https://en.wikipedia.org/wiki/Mandala) : But in the Guhyagarbha tantra, outlined in [Luminous Essence: A Guide to the Guhyagarbha Tantra](https://wisdomcompassion.org/wp-content/uploads/2019/10/Luminous-Essence-A-Guide-to-the-Guhyagarbha-Tantra.pdf) , it is said: > The _subject matter_ of this tantra is the **maṇḍala of the ground**, the ultimate natural state of all phenomena, which is primordially of an enlightened nature within great purity and equality. Moreover, the tantra also shows the path, the various means that allow one to actualize this ground either directly or indirectly. Finally, the tantra reveals the maṇḍala of the fruition—perfect, total purity. In short, the tantra teaches the profound realization of mantra, as subsumed within ground, path, and fruition. Where can I find more information on this deeper meaning of mandala. What is the mandala of the ground?

Somehow, I seem to be forming mandalas within my psyche without any particular knowledge of how I'm doing so. I'm merely walking around, or meditating, and there will occur mandalas of great complexity (usually of the same shape) which arise in my mind. When they do, my mind will explore and think about them, almost obsessively, and attempt to understand them. Any idea about this?

I have heard of and seen sand mandalas in Tibetan Buddhism. Here is a picture: **I have two questions, which are related:** 1. I have heard that upon completion they are erased to represent transience. Is this what the erasure represents? 2. What other spiritual significance does the mandala have in Tibetan Buddhism. I seem to remember something relating to a spiritual journey being represented in the mandala yet I am unsure. I would like clarification on this.
