Kṣānti, translated here as tolerance and elsewhere frequently as patience or forbearance, has been a central virtue throughout the long history of Buddhism. It was one of the ten perfections of the Buddha praised in the early Pali sutras and continued to develop in range and significance in the unfolding of Mahayana Buddhism. Śāntideva goes so far as to claim that “there is no spiritual practice equal to tolerance.” Then, having given more cursory treatment to the first two perfections – generosity and morality – he backs his claim by devoting a full chapter to the perfection of tolerance. There and elsewhere we begin to see the qualities of human character encompassed by the perfection of tolerance.

Kṣānti means “unaffected by,” “able to bear,” “able to withstand,” and in that dimension indicates a strength of character, a composure, and a constancy of purpose that allow a bodhisattva to continue pursuing universal enlightenment in spite of enormous difficulty. Emphasizing that basic dimension, this third perfection could also be translated as the “perfection of endurance” or the “perfection of composure.” Bodhisattvas who have trained in this virtue are imperturbable and well-composed, calm and focused in the midst of adversity. Through deliberate self-cultivation, they build the capacity to withstand danger, suffering, and injustice, to resist the onslaught of negative emotions, and to think clearly under the stress of turmoil. They attain an “admirable constancy” that, even in face of enormous opposition, equips them to move effectively when others have been overwhelmed.

From the earliest periods of Buddhist history, morality (śilā) was understood to be fundamental to the practice, often interpreted as the starting point of the Buddhist path or as a prerequisite for it. The early Buddhist monastic community organized itself around a set of ten precepts and a much more detailed set of monastic rules (vinaya) that served to guide practitioners and establish them in a very specific form of life. These were broadened and adapted to the lives of lay followers in separate lists and codes of virtue specifically tailored to the circumstances of nonmonastic life. Regardless of these differences, however, morality was considered fundamental to Buddhist practice. … The most basic moral teaching for Buddhist monks and nuns, and therefore the one most committed to memory, is a list of ten precepts, the first five of which constitute the moral fundamentals of the laity. These require that a Buddhist refrain from (l) harming living creatures, (2) taking what has not been given, (3) inappropriate sexual activity, (4) false speech, (5) intoxicants that lead to carelessness, (6) eating after midday, (7) attending entertainment, (8) wearing jewelry or perfume, (9) sleeping on luxurious beds, and (10) handling money. These precepts are considered “paths of training” (śiksā-pada) because they function not just to prohibit immoral behavior but also, more importantly, to transform the character of the practitioner. In fact, in all forms of Buddhism, morality is “perfected” when an enlightened motivation takes hold, a motivation in which moral rules are no longer the focus of attention. When nonattachment, compassion, and wisdom prevail in the mind, then morality is thought to function naturally without recourse to rules and prohibitions. The precepts are part of the path of training meant to inculcate states of mind from which moral action might one day flow naturally. …

[T]en virtuous acts (daśakusala).

The ten acts of virtue are applicable to all Buddhists, monastic and laity, and are typically taught in terms of restraints on body, speech, and mind. These include abstention from (l) killing, (2) stealing, (3) sexual misconduct, (4) lying, (5) slander, (6) harsh, derogatory speech, (7) frivolous speech, (8) covetousness, (9) anger and malice, and (10) false views. The first three recommend restraint for the body, the next four delimit speech, and the final three refer to states of mind.

Mahayana Buddhist sutras maintain that the most admirable human beings, bodhisattvas at the highest level, are characterized by a profound, universal compassion, compassion so far-reaching that their daily actions demonstrate as much concern for the well-being of others as for themselves. In order to pursue the Buddhist ideal of compassion at this exalted level, practitioners train themselves in the perfection of generosity. Generosity of spirit – the capacity to give of oneself in a wide range of creative ways – has been an important dimension of Buddhist self-cultivation throughout the long history of this tradition.
