One day, while ZM Yi-shan is taking a bath, because the water is too hot, he called his students to bring a pail of cold water to add in.
Following his order, a student brought the water to add cold to the hot water, then poured away the remaining water.
ZM said unhappily: Why are you so wasteful? In this world, no matter what material or matter, have their own use, only difference is price big or small.
You so easily poured away the remaining water, that is One drop of water if use to water flowers, grass, trees, not only they are happy, and the water itself won't lost its value, why so wasteful?
Even if its a drop of water, its value is infinitely big.
弟子听后若有所悟，于是将自己的法名改为 “滴水”，这就是后来非常受人尊重的 “滴水和尚”。
Upon hearing these, the student has some realisation and changed his name to Water droplet, this one became well respected in later years as the Water droplet monk.
Later, when Water droplet monk propagate dharma, some asked him:
In this world, what has the greatest merits?
Monk answered: Drop of water!
The Void engulfed all, what can engulf the Void?
Drop of water!
Hence forth, the monk has merged heart into drop of water, heart engulfing the great void, within a drop of water there is infinite space and time.
I have said that Tantrayana is Immeasurable & Infinite. :)
Now, do you know what I mean?
