I'm referring to the chapter in the Avatamsaka. Here is one summary:
- The Great Samadhi of Universal Light
- The Great Samadhi of Wondrous Light
- The Great Samadhi of Sequentially Going throughout all Buddhalands
- The Great Samadhi of Purifying the Activities in the Depths of the Mind.
- The Great Samadhi of the Magnificent Treasury of Knowing the Past.
- The Great Samadhi of a Treasury of Wisdom Light
- The Great Samadhi of Fathoming the Adornments of Buddhas in all Worlds.
- The Great Samadhi of Distinguishing the Bodies of Living Beings.
- The Great Samadhi of Ease and Comfort in the Dharma Realm.
- The Great Samadhi of the Unhindered Wheel.
Here is outline of the whole thing that mentions the 10 Samadis.
3 is clear enough, there is a chapter in the Avatamsaka that does this, (chapter 4 I think).
5, 7, and 8 are results of meditation rather than steps leading to it.
Were these Samadhi's something that a lay or monastic bodhisattva would be expected to practice, or are these Samadhis that an already enlightened or nearly englightened Bodhisattva would engage in?
(Sorry I don't have a link to the full text, I only know of the Cleary translation which is available on Amazon.)
