“Arisen beneath a triple mystic heaven
The seven immortal earths were seen, sublime:
Homes of the blest released from death and sleep
Where grief can never come nor any pang
Arriving from self-lost and seeking worlds
Alter Heaven-nature’s changeless quietude
And mighty posture of eternal calm,
Its pose of ecstasy immutable.” pg.672
The triple mystic heavens are the three higher worlds, Satloka, Chidghana or Tapoloka, Anandaloka. The seven immortal earths are the seven grounds of being based on the seven principles of existence. These seven principles are differentiated in the Supermind. Here only they dwell who are released from death and grief and sleep.
Affectionately,
