On a recent Saturday night at the performance space Littlefield in Gowanus, Brooklyn, the singer Bette Smith moved effortlessly across the stage wearing a tight holographic vinyl dress and five-inch-heeled thigh-high boots, strutting like Tina Turner . Since her start at age 5 singing in church, Ms. Smith has performed at the Montreux Jazz Festival in Switzerland and toured Europe multiple times. She is currently on tour in Spain. But when Ms. Smith is in New York, she spends her Sundays meditating, volunteering and taking hot yoga classes. She lives in Park Slope, Brooklyn, with her Australian Labradoodle, Jeremiah.

SECRET MANTRA I get up at 6 and I meditate for about 20 minutes. I have a secret mantra, which I use to zone in and get into a rounded state of being. It helps my concentration, memory and overall well-being. I study Transcendental Meditation. Oprah does it. Ellen DeGeneres does it. Stevie Wonder wrote a song about it. The Beatles did it. My mentor says I’m hyper, so after I meditate for 20 minutes, I then take another 10 minutes to just come back into my body.
