My sons [, that is, the Bodhisattvas]
Who seek

Who believe that they will become Buddhas definitely,
And who have compassion towards others,
May be likened to the short {small} trees.

The Greater Vehicle has the connotation of “covering [in this sense] it is similar to trees. [Those who are in] the seventh stage (bhūmi) and [those who are] below are referred to as small trees whereas [those who are in] the eighth or above are spoken of as great trees.
