Insect

The narrator of Poul Anderson's The Avatar, VI, p. 55, has been a crawling caterpillar, a sleeping pupa and a flying moth. He sensed his environment but did not remember his former forms.

The caterpillar sensed crisp sweet juicy leaves, warm sunlight, cool dew and endless odors. The moth saw vague shapes but knew more by fragrance. He ate nectar and sap. Flying by night, he and his flock saw what he later learned were the lights of men.

Gathered up into Oneness, he says that "We" knew his whole life from the egg. "The One" is my term for the cosmic totality that is also the object of religious experience but Insect means something more specific.
