An old glass plate used for years to catch overflow and drips from potted plants. Hence the film along the outer edges. Waiting on the lower shelf of the plant stand for its next client.
Today’s kasiṇa. “For now we see through a glass, darkly; but then face to face: now I know in part; but then shall I know even as also I am known.” (1 Corinthians 13:12)
From Buddhaghosa’s section on subjects for meditation in The Path of Purification.
[THE LIGHT KASIṆA]
21. Of the light kasiṇa it is said: “… the sign arises in him when he sees the circle thrown on a wall or a floor by sunlight or moonlight entering through a hole in a wall, etc., or when he sees a circle thrown on the ground by sunlight or moonlight coming through a gap in the branches of a dense-leaved tree or through a gap in a hut made of closely packed branches.
…23. Here the learning sign is like the circle thrown on the wall or the ground. The counterpart sign is like a compact bright cluster of lights.
I haven’t reached either the learning sign or the counterpart sign, yet. Just at the preliminary-work sign, trying to form a firm mental image of the circle of light, but having to look back at the circle on the rug “to develop this sign,” with most of the effort going “toward being mindful fo the object, noticing when a distraction or other hindrance has arisen, applying the antidote, and bringing the mind back to the meditation object.” Dalai Lama, Thubten Chodron.
