In the literature we have found correspondence of several significant traits of Jewish mysticism with traits of Buddhism and other systems of Indian religion-philosophy. Among the corresponding traits is the fundamental idea of emptiness or nothingness, shuunyataa in Sanskrit, ayin in Hebrew. Also corresponding are attempts to harmonize the idea and experience of emptiness with fullness, and with the experience of the secular world with its many things and concepts. We list eight significant traits of Jewish mysticism, which we find (...) correspond with traits of Indian religion-philosophies. We also discuss some important relations of these Indian and Jewish belief systems with modern science. We contend, that natural science is built on spontaneous sensory experiences; on this basis concepts and theories are constructed. Likewise we think, that spiritual experiences occur spontaneously and contribute to the basis of religious, mystic and some philosophical belief systems. We thus think, there are important parallels between scientific and spiritual cognition. Key words: Comparative religion; Emptiness/fullness; nothingness; God; compassion; reincarnation; cognition, scientific spiritual; spiritual experiences; Buddhism. (shrink)
