Spiritual Cultivation Aims to Transform the Eight Consciousnesses into the Four Wisdoms

We will now discuss the "Three Bodies and Four Wisdoms". The Three Bodies—the Dharmakaya (Dharma Body), Sambhogakaya (Reward Body), and Nirmanakaya (Response Body)—are innate to all sentient beings, and are fully actualized upon enlightenment. The Four Wisdoms refer to the transformation of the Eight Consciousnesses into the four wisdoms: the Great Mirror Wisdom, the Equal Nature Wisdom, the Wonderful Observation Wisdom, and the Accomplishing Action Wisdom. This is foundational Buddhist knowledge. We ordinary beings burdened by karmic afflictions function entirely within the domain of the mind, intellect, and consciousness: the "mind" refers to the eighth Alaya (Store) Consciousness, the "intellect" refers to the seventh Manas Consciousness, and the "consciousness" refers to the sixth discriminating consciousness—this grouping is precisely what is referred to as the mind, intellect, and consciousness.

The first five are the sense consciousnesses of the eye, ear, nose, tongue, and body; together with the sixth, seventh, and eighth consciousnesses, these make up what are called the Eight Consciousnesses. The Eight Consciousnesses are the "mind kings", accompanied by 51 mental factors, all of which are elaborated on in detail in the Treatise on the Hundred Dharmas (Bai Fa Ming Men Lun).

The essence of spiritual practice is the transformation of the Eight Consciousnesses into the Four Wisdoms. Where should one begin this work? By severing discriminative thought and attachment.

The sixth consciousness is the consciousness of discrimination: whenever we encounter any phenomenon, we immediately judge it as good or bad, beautiful or ugly, right or wrong, large or small. This kind of discriminative thinking is what is known as the imputed nature of delusion. We must transform this discriminative thinking into non-discriminating awareness. Non-discrimination means transcending all binary oppositions; at the fundamental level of our inherent nature, none of these value judgments exist at all.

The seventh consciousness is the Manas consciousness, which is characterized by attachment: it clings to a false sense of self, taking the perceiving aspect of the Alaya Consciousness as the self, and treating the first six consciousnesses as tools for the self's use. For this reason, the Manas consciousness is also called the "transmitting consciousness". As the Avatamsaka Sutra records, the first words the Buddha spoke after attaining enlightenment were: "Marvelous! Marvelous! All sentient beings on earth possess the wisdom and virtues of the Tathagata, yet they cannot realize this truth only because of their discriminative thinking and attachment. If they abandon discriminative thinking and attachment, their innate natural wisdom, all-pervading universal wisdom, and untaught wisdom will immediately manifest."

This discriminative thinking corresponds to the sixth consciousness, while attachment corresponds to the seventh consciousness. Thus, the entirety of spiritual practice consists in breaking free from discriminative thinking and dissolving attachment. When we transcend discriminative thinking, the sixth consciousness transforms into the Wonderful Observation Wisdom. This wisdom is the sublime functioning of prajna, or perfected wisdom. When the Buddha teaches the Dharma and expounds the scriptures, he uses the Wonderful Observation Wisdom to discern the unique capacities and dispositions of each sentient being, and teaches Dharma methods suited to their individual needs. He relies on this wisdom, but he does not engage in deluded discriminative discernment: even though he has complete, perfect understanding of all phenomena, he does not generate false, discriminative perceptions. Then, the seventh consciousness transforms into the Equal Nature Wisdom.

This "equality" refers to the principle of emptiness: what is referred to as the "single mark" (a unified, undifferentiated essence) constitutes true equality. This single mark is the mark of no-mark, which is the essence of emptiness. Only through direct realization of emptiness, the mark of no-mark, and this unified nature can one attain this equal nature, thereby completing the transformation of this consciousness. Once the sixth and seventh consciousnesses are transformed during the causal stage of practice (the bodhisattva path prior to full enlightenment), the eighth consciousness will naturally transform into the Great Mirror Wisdom at the stage of fruition (full buddhahood), and the first five consciousnesses will transform into the Accomplishing Action Wisdom. This process of transforming the basis of consciousness (the fundamental shift in one's cognitive and perceptual framework) is extremely difficult to achieve through self-power alone.

Take the case of trying to force ourselves to stop all discriminative thinking: we end up attached to the very idea of "not discriminating"—this attachment itself creates a new set of binary oppositions. If we strive to focus on emptiness, we end up attached to the concept of emptiness itself; in fact, even this attachment to emptiness must be released, and even the conceptual mark of emptiness cannot be clung to. This is precisely why this path is so arduous for ordinary beings. However, if one is reborn in the Western Pure Land of Amitabha, simply hearing the Buddha's prophecy of one's future enlightenment and receiving the blessings and empowerment of all Buddhas is enough to transform the Eight Consciousnesses into the Four Wisdoms. This is the power of the Buddha's immense blessings and support.
