As for the spiritual worlds:
Likewise the rewards of the other world are the eternal life which is clearly mentioned in all the Holy Books, the divine perfections, the eternal bounties, and everlasting felicity.
The rewards of the other world are the perfections and the peace obtained in the spiritual worlds after leaving this world; whilst the rewards of this life are the real luminous perfections which are realized in this world, and which are the cause of eternal life, for they are the very progress of existence.
It is like the man who passes from the embryonic world to the state of maturity, and becomes the manifestation of these words: “Blessed be God, the best of creators.” The rewards of the other world are peace, the spiritual graces, the various spiritual gifts in the Kingdom of God, the gaining of the desires of the heart and the soul, and the meeting of God in the world of eternity. In the same way the punishments of the other world, that is to say, the torments of the other world, consist in being deprived of the special divine blessings and the absolute bounties, and falling into the lowest degrees of existence.
He who is deprived of these divine favors, although he continues after death, is considered as dead by the people of truth.
(Abdu’l-Baha, Baha’i World Faith – Abdu’l-Baha Section, p. 324)
——
And before you ask about “the divine perfections”:
When a soul has in it the life of the spirit, then does it bring forth good fruit and become a Divine tree. I wish you to try to understand this example. I hope that the unspeakable goodness of God will so strengthen you that the celestial quality of your soul, which relates it to the spirit, will for ever dominate the material side, so entirely ruling the senses that your soul will approach the perfections of the Heavenly Kingdom. May your faces, being steadfastly set towards the Divine Light, become so luminous that all your thoughts, words and actions will shine with the Spiritual Radiance dominating your souls, so that in the gatherings of the world you will show perfection in your life.
Some men’s lives are solely occupied with the things of this world; their minds are so circumscribed by exterior manners and traditional interests that they are blind to any other realm of existence, to the spiritual significance of all things! They think and dream of earthly fame, of material progress. Sensuous delights and comfortable surroundings bound their horizon, their highest ambitions centre in successes of worldly conditions and circumstances! They curb not their lower propensities; they eat, drink, and sleep! Like the animal, they have no thought beyond their own physical well-being. It is true that these necessities must be despatched. Life is a load which must be carried on while we are on earth, but the cares of the lower things of life should not be allowed to monopolize all the thoughts and aspirations of a human being. The heart’s ambitions should ascend to a more glorious goal, mental activity should rise to higher levels! Men should hold in their souls the vision of celestial perfection, and there prepare a dwelling-place for the inexhaustible bounty of the Divine Spirit.
(Abdu’l-Baha, Paris Talks, p. 98)
