In the beginner's mind there are many possibilities, but in the expert's there are few. So begins this most beloved of all American Zen works. Seldom has such a small handful of words provided a teaching as rich as this famous opening line of Shunryu Suzuki's classic. In a single stroke, the simple sentence cuts through the pervasive tendency students have of getting so close to Zen as to completely miss what it's all about. An instant teaching in the first minutes. And that's just the beginning.

What Is Zen is the quintessential beginner's guide to achieving enlightenment. In simple, often poetic language, the author offers a general introduction to the concepts and philosophy of Zen Buddhism. He describes what it is, how it began and evolved, and how its emphasis on simplicity and self-effacement have helped shape an aesthetic found throughout Japanese culture.

The Lankavatara Sutra, dating from the early years of the Common Era, sometime before 443, is one of the most important Mahayana Buddhist texts, not least because of its influence on later Tibetan, Chinese and Japanese Buddhism. One of its possible early translators in the 8th century was Gunabhadra, who is sometimes regarded as the first father of Zen in China. The Sutra takes the form of a dialogue between the Buddha in his cosmic form (as opposed to the historical figure of the Pali Canon) and the Bodhisattva or ‘Great Being', Mahamati.

Raised in a rationalist household in Oxford during the spiritual heyday of the '60s and '70s, an unexpected spiritual awakening would prompt a lifelong quest to integrate the experience into his life, leading him eventually to Zen Buddhism. As Shukman gets to grips with meditative practice and struggles with anxiety, depression and the chronic eczema he had had since childhood, he discovers in surprising ways the emotional, spiritual and even physical healing that he has been searching for all along.

When the Bodhisattva Avalokitesvara was engaged in the practice of the deep Prajnaparamita, he perceived that there are the five Skandhas; and these he saw in their self-nature to be empty. "O Sariputra, form is here emptiness, emptiness is form; form is no other than emptiness, emptiness is no other than form; that which is form is emptiness, that which is emptiness is form."
