There is no need to fall into meaningless and unproductive pessimism. All these problems are caused by human beings, which means that they must have a human solution. However long the effort takes, if we do not abandon the work of unknotting the tangled threads of these interrelated issues, we can be certain of finding a way forward.

Daisaku Ikeda

If our lives are always smooth sailing, we’ll never be able to savor real happiness. It goes without saying that the treasure of happiness cannot be found in a life of ease and idleness. The diamond of happiness can be found only by making our way into the deep mountain recesses of life with great effort and exertion.

Daisaku Ikeda

In addition, when we struggle with and chant about how to share Buddhism with others and to realize our goals for kosen-rufu, we are already expressing the life state of the Bodhisattvas of the Earth. Through such efforts, therefore, we can overcome and solve our individual problems as well.
