Six at the beginning means:
To spread white rushes underneath.
When a man wishes to undertake an enterprise in extraordinary times, he must be extraordinarily cautious, just as when setting a heavy thing down on the floor, one takes care to put rushes under it, so that nothing will break. This caution, though it may seem exaggerated, is not a mistake. Exceptional enterprises cannot succeed unless utmost caution is observed in their beginnings and in the laying of their foundations.
