The Islands of the Blest

Seven mentions:

A seeker of the islands of the Blest,
He leaves the last lands, crosses the ultimate seas,
He turns to eternal things his symbol quest;
     — Book 1 Canto 4

The seven immortal earths were seen, sublime:
Homes of the blest released from death and sleep
     — Book 11

The Fortunate Isles or Isles of the Blessed (μακάρων νῆσοι, makárōn nêsoi) are mentioned by Hesiod when he refers to the fourth race, “a god-like race of hero-men who are called demi-gods, the race before our own, (…) And they live untouched by sorrow in the islands of the blessed along the shore of deep swirling Ocean, happy heroes for whom the grain-giving earth bears honey-sweet fruit flourishing thrice a year, far from the deathless gods, and Cronos rules over them;

If the Titan Cronos is the lord of this place, it is because the corresponding parts in the seeker are no longer under the domination of the mind (far from the deathless gods).

Homer mentions only the Elysian Fields (Odyssey, 4.560-565).

Elysium, otherwise known as the Elysian Fields, Ἠλύσιον πεδίον, means, based on the symbolism of its consonants: (πέδον + Ι+ Ἠλύσιον), “the land of consciousness where the human spirit is free”. That is, liberation of the spirit as defined by Sri Aurobindo.

This confirms what is said in this study of the demigods.

Most authors have identified the Elysian Fields with the Isles of the Blessed.

These two regions are associated with liberation of the spirit, and with the great overthrow of Yoga illustrated by the Trojan War, but it is not possible for us, for want of further evidence, to distinguish them with certainty.
