Imam Khomeini in this regard explains as follwoing:
If you are among the people of strong will power and an open heart, and the worldly desires have not driven their tentacles deep into it, and if the worldly allurements and ornaments have not blinded it by their light, and if you are still capable of judging and criticizing yourself with justice, the suggestions given in the previous chapter can be most useful for you in this regard.
But if you have not reached this level, it is better for you to meditate upon your state; it is possible that your heart may wake up. O man, who were initially nothing; who were hidden in the folds of nothingness for ages and epochs, more insignificant than nothingness itself and absent from the realms of existence, when God Almighty resolved to create you, you were the most deficient of the recipients, mean, and insignificant. You were incapable of receiving the Divine effusion (fayd).
He created you from the matter (hayula) of the universe, which is absolute potentiality and pure weakness, and moulded you into an elemental bodily form, which was the lowest, and the meanest of the existents of the universe.
After that you were given the form of sperm, which you will loathe to touch it and will take great pains for cleansing your hands if by chance they are made dirty by it. Then you were kept in a very narrow and unclean place, the twin reproductive glands of the father.
And after that through the urinary tract in a terribly ugly state you were brought into the mother’s womb and you were given such a place to live in, that description will be disgusting to you.
After being placed there, you were given the form of a fetus and a lump of clotted blood. There you were nourished with such a food that you will go mad if you are told about it, and will feel ashamed. But since everyone has to pass through this tribulation, it abates our shame of it.
A distress, which is common, becomes tolerable.
