The aspect of focusing on mental repetition of words or phrases may be combined with focus upon an external image. In Eastern traditions, this may take a Mandala form, such as the Shri Yantra, below. To use this form of visual meditation, focus your attention on the central [bindu] point and allow your eyes to soft focus. Try to minimize blinking, but don’t let your eyes get too dry. When combined with a mantra, this can be a powerful tool to focus attention and still the mind.

This sign looks like a Mandala sign in Tibetan Buddhism. I looked in to the center and it is amazing that it did make me concentrate. I never knew a Mandala could be used this way. Thank you so much!
It actually is a mandala type pattern. You are absolutely correct that staring at the bindu point can provide an experience of a different perspective of the diagram. Thank you for sharing!
