There is a kind of "great drink" in Zen. Those ancestors and bodhisattvas sometimes use "stick drinks" to enlighten their disciples. When a Zen Buddhist is suddenly hit by a stick, he may wake up and be inspired. There are many such stories and cases in Zen classics.
The "big drink" of the ancestor Bodhisattva is sometimes similar to the teacher hitting the students who doze off in class with a pointer, which is goodwill and concern.
