Zen was uniquely suited to the Samurai of Japan. The high moral principles of Buddhism, when adopted and adapted by the Japanese warriors who became the Samurai, created an austere philosophy of singular beauty and depth. Its characteristic requirements of strict control over body and mind was exemplified by ancient warrior monks whose serene countenance, even in the face of certain death, made them much admired even by their foes.Zen may be the most misunderstood of the world's moral philosophies. While it is often classified as a Religion, it is frequently considered by its adherents to be a utilitarian philosophy, a collection of rational moral precepts or, even more simply, as a state of being. The aim of the practice of Zen is to become Enlightened and achieve the beatitude of Nirvana.To reach Nirvana means to achieve the state of extinction of pain and the annihilation of sin. Zen never looks for the realization of its beatitude in a place like heaven, nor believes in the realm of Reality transcendental of the phenomenal universe, nor gives countenance to the superstition of Immortality, nor does it hold the world is the best of all possible worlds, nor conceives life simply as blessing. It is in this life, full of shortcomings, misery, and sufferings, that Zen hopes to realize its beatitude. It is in this world, imperfect, changing, and moving, that Zen finds the Divine Light it worships. It is in this phenomenal universe of limitation and relativity that Zen aims to attain to highest Nirvana.

The author interprets Zen Master Shunryu Suzuki's account of Zen practice from a Kantian perspective in order to explore the deep connection between Zen meditation, or zazen, and respect for universal moral principles. The author shows that both Shunryu Suzuki and Kant posit a reciprocally supportive relationship between the development of personal autonomy and the respectful observance of moral rules or precepts, and that both see the practice of a discipline restricting the speculative activity of reason as essential to the attainment of true freedom and moral worth. By cultivating consciousness of freedom through insight into emptiness, the discipline of zazen acts as what Kant calls a "moral ascetic," cultivating a mind and body responsive to universal moral concerns. Olson concludes by showing how Kant's notion of the ultimate end of moral behavior—the highest good—is manifested in the Bodhisattva's vow to work for the salvation of all sentient beings.

When the Buddha established his community over twenty-five centuries ago, he did so upon a foundation of radical equality among women and men. And indeed, the earliest Buddhist scriptures celebrate the teachings and inspiring influence of these path-blazing female renunciants. Nonetheless, through much of the Buddhist world, the order of nuns has disappeared or was never transmitted at all. Dignity & Discipline represents a watershed moment in Buddhist history, as the Dalai Lama together with scholars and monastics from around the world, present powerful cases, grounded in both scripture and a profound appeal to human dignity, that the order of Buddhist nuns can and should be fully restored.
