As muddy water is best cleared by leaving it alone, it could be argued that those who sit quietly and do nothing are making one of the best possible contributions to a world in turmoil.
The more we grow in love and virtue and holiness, the more we see love and virtue and holiness outside. All condemnation of others really condemns ourselves. Adjust the microcosm (which is in your power to do) and the macrocosm will adjust itself for you. It is like the hydrostatic paradox, one drop of water can balance the universe.
The talker has found a hearer but not a listener; and though he may talk his very best for his own sake, you will find that his mental movements are erratic: they have no fixed centre and no definite object. His talk is like the water of a canal whose banks have given way, which rolls aimlessly hither and thither, without fulfilling any useful function, though it is the same water which was so helpful and serviceable, when it was confined within clearly marked limits by the restraining force of its earthy boundaries.
Do not overlook tiny good actions, thinking they are of no benefit; even tiny drops of water in the end will fill a huge vessel. Do not overlook negative actions merely because they are small; however small a spark may be, it can burn down a haystack as big as a mountain.
Even a vortex is a vortex in something. You can't have a whirlpool without water; and you can't have a vortex without gas, or molecules or atoms or ions or electrons or something, not nothing.
