At the beginning of meditation, there’s often a flurry of thought as the tautness of the spring of the mind unwinds and settles.
Do not worry about this flurry of thought. It does not mean you cannot meditate, that your mind is too busy to grow quiet.
It is a natural occurrence of the mind settling.
This unfurling of the mind is a necessary step as we fall into meditation.
