67. [Sanskrit available] He gets a cool composure of his mind; like the coolness at the close of a hot summer-day, who shuts out from his view the reflections of all worldly objects.

68. [Sanskrit available] Look on this universe, O sinless Rama, as one common display of Divine light, like the appearance of day light which is common to all; it is the mind which taints it with various forms, as the sun-beams are reflected in sundry piece by objects.
