How to Transform the Basis into Tathāgatagarbha?

Transforming according to the Tathāgatagarbha means that all bodily, verbal, and mental actions, as well as the nature of the mind of the five aggregates body, must take refuge in the Tathāgatagarbha, resembling the Tathāgatagarbha, transforming the defiled, afflicted, and ignorant nature of the five aggregates body into the pure, selfless nature of the Tathāgatagarbha. How is the Tathāgatagarbha pure? For example, the Tathāgatagarbha is free from afflictions like greed; it does not crave wealth, sensual pleasures, fame, food, or sleep. It does not become covetous upon seeing money, nor does it scheme to earn, deceive, or extort money. The five aggregates body and the seven consciousness minds must also be like this. It does not stir upon seeing forms, whether male or female, beautiful or ugly, remaining unmoved like wind passing through flowers, not a single leaf clinging to it. The five aggregates body must also be like this. It does not crave fame, does not seek renown, does not enjoy showing off or making a display, does not seek flattery or reverence, and remains obscure and unknown. The five aggregates body must also be like this. In daily life, the Tathāgatagarbha is not extravagant or attached to necessities like eating, drinking, excretion, walking, standing, sitting, lying down, or any other means of sustenance; it uses them without attachment. The five aggregates body must know contentment, avoiding extravagance, waste, comparison, and pretentiousness. The Tathāgatagarbha never sleeps and does not seek enjoyment. The five aggregates body must not crave the comfort of sleep, not pursue leisure and ease, and must abandon the affliction of sleep. If one cannot accomplish these, then one has not taken refuge in the Tathāgatagarbha, and even if one wishes to transform according to it, one will not succeed.
