Should you chant a mantra or sit in silence? The answer depends on your temperament, your current state, and what you are trying to achieve. Here is an honest comparison from someone who practices both daily.
Two Approaches to the Same Silence The meditation world is full of debates, but few are as persistent as this one: is it better to meditate with a mantra or in silence? Transcendental Meditation practitioners swear by their mantras.
Vipassana practitioners insist that silent observation is the purest path. Zen practitioners sit in shikantaza - "just sitting" - while devotees of Krishna chant the Maha Mantra for hours.
Having practiced both approaches extensively for over thirty years, I can tell you that the debate itself is somewhat misguided.
Both mantra meditation and silent meditation are powerful tools, but they work through different mechanisms and serve different purposes.
