Nembutsu is a practice in Pure Land Buddhism that involves the recitation of the phrase "Namu Amida Butsu," which translates to "I take refuge in Amida Buddha." This practice is believed to help practitioners focus their thoughts on Amida Buddha, who is regarded as a compassionate figure that can lead individuals to enlightenment and rebirth in the Pure Land. The Nembutsu can be recited silently or aloud and is often performed as a form of meditation or prayer. It serves as a way for followers to express their faith and devotion, seeking guidance and support from Amida Buddha in their spiritual journey.
