Clearing off my half-read pile this month, so have gone back to The Tibetan Book of Living and Dying by Sogyal Rinpoche. (I think I have been going through this so slowly because I keep scurrying off to look things up.) I'd heard of garudas before, but not the Tibetan significance: Because they are born fully grown, they represent our primordial nature, which is already completely perfect. Wing feathers are fully developed in the egg. but it cannot fly until it hatches. The garuda is mentioned in the context of the bardos, so in this case it is pointing to the opportunity for liberation at death, i.e., once the body is discarded, the qualities of buddhahood will be 'radiantly' displayed.
I haven't yet figured out how to post a properly sized image in this software yet, but here's a great one: from the site linked above - http://www.fodian.net/world/garuda/garuda2.jpg. These look a lot like gryphons to me!
From Wikipedia: In Buddhist mythology, the garuḍas (Pāli: garuḷā) are enormous predatory birds with intelligence and social organization. Another name for the garuḍa is suparṇa (Pāli: supaṇṇa), meaning "well-winged, having good wings". Like the Nāgas, they combine the characteristics of animals and divine beings, and may be considered to be among the lowest devas.
Alright world..... watch out for my beak.
