May God us keep
From Single vision and Newton's sleep
- William Blake

Whoever wishes,
May he sit in meditation
With eyes closed
To verify if the universe be true or false.

I, in the meanwhile,
Shall sit with insatiate eyes
To see the universe
While the light lasts.
- R. Tagore, Our Universe (I. Dutt, translator, Jaico, Bombay (1969)
