How Does Tathāgatagarbha Produce the Five Aggregates and the Eighteen Elements?

The eighteen dhātus are born from the tathāgatagarbha, and they stand in a relationship with the tathāgatagarbha of neither being the same nor different. The tathāgatagarbha outputs the four great element seeds of earth, water, fire, and wind, forming the aggregate of form of the five faculties of sentient beings, and forming the six sense objects of form, sound, smell, taste, touch, and material form included in the realm of dharmas, including the universe of the vessel-world in which sentient beings live—all the environments for existence. The tathāgatagarbha outputs the consciousness seeds of the manas, sustaining the existence and functioning of the manas, and then outputs the seeds of the six consciousnesses, producing the six consciousnesses; in this way the five aggregates and eighteen dhātus of sentient beings are formed. When we observe our own five aggregates of body and mind, we know that they are all born after the fact, and whatever is formed after the fact is subject to arising and ceasing; it is fundamentally not the true self. The true self could not possibly be constantly arising and ceasing, so lacking in self-mastery (avaśatā). The true self must certainly be one that can exist by its own mastery, and moreover is without feelings of suffering.
