The Profound Yogācāra Meaning of the Diamond Sutra (68)

After attaining enlightenment through receiving and upholding the Diamond Sutra, one's wisdom grows ever greater, and one gains the ability to expound the Dharma for others, enabling them to attain enlightenment as well. The merit of the Dharma-giving itself is very great, and when sentient beings benefit from it, the merit becomes even greater. Throughout the three incalculable eons required to accomplish the Buddha-way, by liberating sentient beings from the suffering of birth, old age, sickness, and death, and forming karmic connections with countless sentient beings, one will in the future have numerous disciples who follow and learn from one, and upon this foundation one can establish one's own Buddha-land. The establishment of a land must be composed of disciples at various levels; without disciples, one cannot establish a land, much less accomplish the Buddha-way. Only by leading disciples in cultivation, and only when those disciples achieve attainment, can one's own cultivation advance to a higher stage and attain a loftier fruition. Therefore, receiving, upholding, reading, and reciting the Diamond Sutra, and awakening to the vajra mind (Vajracitta)—this merit is boundlessly vast.

The vajra mind is also an unconditioned mind, without mental activity pertaining to the three realms, doing nothing. Precisely because it does nothing, it can do everything and accomplish all dharmas. The merit contained within the unconditioned mind is immense; it can never be erased, cannot be destroyed by anyone, and cannot be taken away by anyone. How supreme, then, is this unconditioned merit—it is beyond words, far more supreme than the conditioned merit of giving the seven treasures; it is incomparable and unspeakable.
