Even A Child In Play

“[E]ven a child in play who has built a Stupa for the Buddha out of a heap of sand – all are people who have attained the path of the buddhas.” This means that those who have produced the thought of enlightenment and who are carrying out bodhisattva practice will plant good roots of merit and be able to realize enlightenment. It is not the case that those who have not originally produced the thought of enlightenment, such as ordinary people and the disciples who are fixed [in the Small Vehicle], are able to attain it. The same applies to those such as the ones [who have honored the Buddha] “by nodding their head.”
