"The laughter of the wise is the laughter of freedom. What the wise have understood has freed them from the unnecessary burdens of existence and projects them to regions where an eternal sun shines. And this light, which they have conquered at the cost of so many efforts, the wise have only one desire, to transmit it to those who live near them and come to visit. But how much time is necessary for them to be able to assimilate it! So the only thing the wise can immediately share is the joy they draw from this wisdom, this joy that fills their heart, that overflows from their heart... And their laughter is the expression of this joy, which we can also call love."
