I see imagining the 'ideal' as perfectly natural.
The 'ideal' is, if you like, the perfect seed. To help us evolve in the external visible world to that of the internal invisible world.
Achieving that perfect state within, here and now, may be said to be Nirvana.
Achieving that perfect state without, eventually, through a slower natural evolution, may be said to be achieving Heaven on Earth.
I see imaging the ideal, the perfection, within, to be practising, and even accelerating the human and planetary evolution towards perfection.
That is nature, naturally, at work. That is Creative Intelligence at work.
That is what we are to do. That is Right Thinking. That is Right Doing.
