any commentary which compares to Jainism & Buddhism?

Jain, Jainism. Jainism is the religion of the Jain community and describes the way of life of those who follow the Jina (spiritual victors), human teachers who have attained infinite knowledge and preach the doctrine of moksha (liberation), also called tirthankaras (builders of the bridge across the road of suffering). One of India’s most ancient non-Vedic traditions, widely regarded as the earliest heterodox offspring of HINDUISM, Jainism is often confused with BUDDHISM with which it bears some superficial similarities. Down through the centuries the Jains, however, have succeeded in maintaining their distinctive identity and the integrity of their belief system and way of life within the highly accommodative climate of Hinduism.
Although the beginnings of Jainism are commonly associated with Vardhamana Mahavira, who lived in the sixth century B.C., the Jain literature does not recognize him as founder or prophet, but as the twenty-fourth tirthankara. Jains today have deified him as the last and greatest savior with ideas of sinlessness and omniscience attributed to him. As a religious movement, Jainism seems to have arisen as a reaction to Brahminical Hinduism, and due to its rejection of the authority of the Vedas, is often perceived as a heresy of Hinduism. The Jaina system is opposed to the idea of God as a supreme personal being. The universe itself is regarded as uncreated and eternal, made up of eternal souls (jivas) and eternal elements (ajivas).
Jainism shares with Hinduism belief in karma (moral retribution) and samsara (transmigration of the soul), although these concepts are interpreted in highly fatalistic terms within the theoretical pessimism integral to the Jaina system. It thus posits a very negative view of life in which humanity is trapped within an essentially painful and evil cycle of human existence. Moksha (liberation) from bondage to this cycle of birth and death is through a process of fourteen stages of spiritual evolution, involving rigid, self-denying ascetic practices. The five great vratas (vows) prescribing these ascetic practices are: not to kill, not to lie, not to steal, to abstain from sexual intercourse, and to renounce all worldly attachments.
Ahimsa (nonviolence) is one of the central beliefs and practices of Jainism. This cardinal principle of Jainism received worldwide attention as the essential ethical basis of the Indian movement for national independence as articulated and practiced by its chief architect, Mahatma Gandhi, who was himself deeply influenced by Jain thought and values. The deep reverence for life among the Jain community is reflected in a lifestyle which includes strict vegetarianism and noninvolvement in vocations such as farming, cattle breeding, and the armed forces. Large numbers of them have thus turned to careers in finance, commerce, and banking, making them one of the wealthiest and most influential communities in India.
Although Jainism has a very limited following of about 4.5 million adherents and the vast majority of them live in India, its influence has been powerful and far-reaching. The latter half of the twentieth century witnessed the emergence of an enterprising and influential Jain diaspora in North America, Britain, Africa, and the Far East. The Jain concern for peace, vegetarianism, and the environment contributes to the movement’s universal appeal. The opportunity that Jainism presents for Christian missions is highlighted by the fact that there appears to be no specific Christian ministry directed toward the Jain community to date.
