In his search for a "higher state of consciousness" Presley became fascinated with the occult and metaphysical phenomena. During his spiritual quest everyone around them saw Presley's personality change dramatically from vibrant and playful, to passive and introverted. Presley went through a period of celibacy, in keeping with the teachings of an Indian guru. "He was going through a cleansing period, physically and spiritually... He loved me and deeply wanted to be faithful to me but never felt certain that he could resist temptation. It was a persistent battle, and it even got to the point where he felt he had to resist me." For the next few weeks, Elvis felt the need to withdraw himself from the temptations of sex. He said, "We have to control our desires so they don't control us. If we can control sex, then we can master all other desires." When they were in bed, "he took his usual dose of sleeping pills, handed me mine, and then, fighting off drowsiness from the pills, pored over his metaphysical books." Priscilla was not interested, and recalled Elvis saying "Things will never work out between us, Cilla, because you don't show any interest in me or my philosophies."
