An overactive mind weighs down upon the heart, depressing and eventually smothering it. This is why, in Taiji, we recommend Mind In Dantien: a quietly mindful and vigilant presence in the deep belly, underpinning and buoying up the heart so that it can bloom as it is meant to. Then the dantien is like a bulb drawing nourishment from the Earth through its roots and supplying the flowering heart above it with a sure stream of support and energy. Thoughts in the head will then tend to be elevated and virtuous because they have really started in the heart and simply bubbled up to find expression.
