(Eg.) The second division of Amenti. The celestial field of Aanroo is encircled by an iron wall. The field is covered with wheat, and the "Defunct" are represented gleaning it, for the "Master of Eternity"; some stalks being three, others five, and the highest seven cubits high. Those who reached the last two numbers entered the state of bliss (which is called in Theosophy Devachan); the disembodied spirits whose harvest was but three cubits high went into lower regions (Kamaloka). Wheat was with the Egyptians the symbol of the Law of Retribution or Karma. The cubits had reference to the seven, five and three human "principles".
