The meaning of the word touchstone gives the answer which is, "A basis for comparison; a reference point against which other things can be evaluated". So I suppose another way of saying it is "As the parents are so will be the children". Parents are like a light when all is dark around you. If you follow the light you will heading in the right direction. If we take only that which we know to be good from our parents then we will be a touchstone to our children.
