From a big survey:
Although many Americans are highly religious, they are not dogmatic in their faith. Seventy percent of Americans with a religious affiliation say that many religions - not just their own - can lead to eternal life. Most also think there is more than one correct way to interpret the teachings of their own faith.
Almost two-fifths of Americans report meditating at least once a week. This practice is particularly common among Buddhists, but nearly half of evangelical Protestants and Muslims say they meditate at least weekly. About one-quarter of the unaffiliated report weekly meditation. These patterns may incorporate elements of both Christian and non-Christian traditions.
