Mantras serve as powerful tools in mindful coloring by providing a word, sound, or phrase that can be repeated during the practice. Commonly used in meditation and prayer across spiritual traditions like Hinduism and Buddhism, mantras help to enhance concentration and foster a deeper connection with oneself. By chanting, whispering, or silently repeating a mantra while coloring, individuals can focus their minds, promote inner peace, and set intentions, enriching their overall coloring experience.
