Variant: The religion of the future will be a cosmic religion. It should transcend a personal God and avoid dogmas and theology. Covering both the natural and the spiritual, it should be based on a religious sense arising from the experience of all things, natural and spiritual as a meaningful unity. If there is any religion that would cope with modern scientific needs, it would be Buddhism.
These two statements are very similar, widely quoted, and seem to paraphrase some ideas in the essay "Religion and Science" (see below), but neither of the two specific quotes above been properly sourced. Notable Einstein scholars such as John Stachel and Thomas J. McFarlane (author of Buddha and Einstein: The Parallel Sayings) know of this statement but have not found any source for it. Any information on any definite original sources for these is welcome.
This quote does not actually appear in Albert Einstein: The Human Side as is sometimes claimed.
Only two sources from before 1970 can be found on Google Books. The first is The Theosophist: Volume 86 which seems to cover the years 1964 http://books.google.com/books?id=7pLjAAAAMAAJ&q=1964#search_anchor and 1965 http://books.google.com/books?id=7pLjAAAAMAAJ&q=1965#search_anchor. The quote appears attributed to Einstein on p. 255 http://books.google.com/books?id=7pLjAAAAMAAJ&q=%22natural+and+spiritual%22#search_anchor, with the wording given as "The religion of the future will be a cosmic religion. It should transcend a personal God and avoid dogmas and theology. Covering both the natural and the spiritual, it should be based on a religious sense arising from the experience of all things, natural and spiritual, as a meaningful unity. Buddhism answers this description." An identical quote appears on p. 284 http://books.google.com/books?id=YpsfAQAAIAAJ&q=%22dogmas+and+theology%22#search_anchor of The Maha Bodhi: Volume 72 published by the Maha Bodhi Society of India, which seems to contain issues from throughout 1964 http://books.google.com/books?id=YpsfAQAAIAAJ&q=%22volume+72%22#search_anchor.
A number of phrases in the quote are similar to phrases in Einstein's "Religion and Science". Comparing the version of the quote in The Theosophist to the version of "Religion and Science" published in 1930, "a cosmic religion" in the first resembles "the cosmic religious sense" in the second; "transcend a personal God" resembles "does not involve an anthropomorphic idea of God"; "covering both the natural and the spiritual" resembles "revealed in nature and in the world of thought"; "the experience of all things, natural and spiritual, as a meaningful unity" resembles "experience the totality of existence as a unity full of significance"; and "Buddhism answers this description" resembles "The cosmic element is much stronger in Buddhism". These phrases appear in the same order in both cases, and the ones from "Religion and Science" are all from a single paragraph of the essay.
Context: Buddhism has the characteristics of what would be expected in a cosmic religion for the future: It transcends a personal God, avoids dogmas and theology; it covers both the natural and the spiritual, and it is based on a religious sense aspiring from the experience of all things, natural and spiritual, as a meaningful unity.

1970s
Context: One of the biggest roles of science fiction is to prepare people to accept the future without pain and to encourage a flexibility of mind. Politicians should read science fiction, not westerns and detective stories. Two-thirds of 2001 is realistic — hardware and technology — to establish background for the metaphysical, philosophical, and religious meanings later.
