If Man uses those immaterial members on the desires of his soul and on minor pleasures under the soil of worldly life in the narrow confin of this earthly World, he will decay and decompose in the midst of difficulties in a brief life in a constricted place like the rotted seed, and load the responsibility on his unfortunate spirit, then depart from this World.If, however, he nurtures the seed of his abilities with the water of Islam and light of belief under the soil of worship and servitude to Allah, conforms to the commands of the Qur’an, and turns his faculties towards their true aims, they will produce branches and buds in the World of Similitudes and the intermediate realm; he will be a seed of great value and a shining machine containing the members of an everlasting tree and permanent truth which will be the means to innumerable perfections and bounties in Paradise. And he will be a blessed and luminous fruit of the tree of the universe.

Yes, true progress is to turn the faces of the heart, spirit, intellect, and even the imagination and other subtle faculties given to Man towards eternal life and for each to be occupied with the particular duty of worship worthy of it. Progress is not as the people of misguidance imagine, to plunge into the life of this World in all its minute details and in order to taste every sort of pleasure, even the basest, make subject to the evil-commanding soul all the subtle faculties and the heart and intellect, and make them assist it; to do this is not progress, it is decline.
