Multiple variations of this quote can be found, but the earliest one on Google Books which uses the phrase "friendly or hostile" and attributes it to Einstein is The Complete Idiot's Guide to Spiritual Healing by Susan Gregg (2000), p. 5 http://books.google.com/books?id=XLQ8X67PozAC&lpg=PP1&pg=PA5#v=onepage&q&f=false, and this book gives no source for the quote.
A variant is found in Irving Oyle's The New American Medicine Show (1979) on p. 163, where Oyle writes: 'There is a story about Albert Einstein's view of human existence. Asked to pose the most vital question facing humanity, he replied, "Is the universe friendly?"' This variant is repeated in a number of books from the 1980s and 90s, so it probably pre-dates the "friendly or hostile" version. And the idea that the most important question we can ask is "Is the universe friendly?" dates back much earlier than the attribution to Einstein, for example in Emil Carl Wilm's 1912 book The Problem of Religion he includes the following footnote on p. 114 http://books.google.com/books?id=nWYiAAAAYAAJ&pg=PA114#v=onepage&q&f=false: 'A friend proposed to the late F. W. H. Myers the following question: "What is the thing which above all others you would like to know? If you could ask the Sphinx one question, and only one, what would the question be?" After a moment's silence Myers replied: "I think it would be this: Is the universe friendly?"'

O interview (2003)
Context: I've learned from others' lives... What works in a relationship of very public people is not making the relationship public — keeping it as personal as it can be. It's the only way it is real. I am suspicious of those who have to let the world know how much they love each other. It's a little sad when you have to brag about how much you love someone. That kind of declaration doesn't always reflect the moment of truth between two people who care deeply for each other. When that truth is there, you don't need others to know it. And when somebody truly loves you, you don't even need him or her to be affectionate. Affection is fantastic, but it doesn't necessarily mean there's love — and the public display of affection is often just a show.
