The Awakening of Faith is a short, dense treatise that sets out the core of Mahayana Buddhist thought in a tight, almost geometric order. After verses of adoration, it announces a plan in five parts: an introduction stating why the work was written, a general statement of principles, a long explanation, the practice of faith, and the benefits that follow. Suzuki's 1900 translation renders the central Chinese term as soul or mind, meaning not a separate metaphysical entity but the kernel and ground of all things.
The general statement names the subject. What the Mahayana is, the text says, is the one soul of all sentient beings, which constitutes everything in the world, both the phenomenal and what lies beyond it. This one soul in itself is suchness, the way things truly are; in its relative aspect, through the law of causation, it appears as birth-and-death. From this the treatise draws a triad: the greatness of essence, the greatness of attributes, which it calls the Tathagata's womb holding immeasurable merits, and the greatness of activity that produces all good in the world.
The explanation, the heart of the book, divides the one soul into two aspects that cannot be separated. As suchness, it is the oneness of the totality of things, uncreate and eternal, free of all marks of individuation, which arise only from our confused subjectivity. Suchness is described under negation, in that it is empty of everything unreal and conditional, and under affirmation, in that it is full and self-existent, containing all that is pure. As birth-and-death, the same soul comes forth from the Tathagata's womb and is called the all-conserving mind, which carries within it both enlightenment and non-enlightenment.
From here the treatise develops its psychology of confusion and recovery. Ignorance and suchness are said to perfume each other: ignorance clouds suchness and breeds the sense of separate selves and objects, while suchness, perfuming ignorance, awakens in the mind a loathing of suffering and a longing for peace. Because enlightenment is already the ground of the mind, the long work of practice is described as the gradual clearing of particularisation rather than the building of a wholly new state. The section also refutes mistaken views and marks out the right path for those at different stages.
The fourth part turns practical, for beginners not yet settled in truth. It defines faith in four objects, the fundamental truth of suchness and then the Buddha, the Doctrine, and the community, and it perfects that faith through five practices: charity, morality, patience, energy, and the paired discipline of cessation and insight. Cessation stills the mind's restless sophistries; insight understands cause and transformation; mastered together they steady a person against fear and distraction. The closing part on benefits commends the whole discourse to anyone who would enter the Mahayana path without dread, promising that steady contemplation of it leads toward complete knowledge.
