Yes Will, that answers Retro's question nicely

And the bit I mentioned about two sides of the same coin can be found here:
Three modes of generating an altruistic intention to become enlightened are described--like a king, like a boatman, and like a shepherd. In the first, that like a king, one first seeks to attain a high state after which help can be given to others. In the second, like a boatman, one seeks to cross the river of suffering together with others. In the third, like a shepherd, one seeks to relieve the flock of suffering beings from pain first, oneself following afterward. These are indications of the style of the altruistic motivation for becoming enlightened;
in actual fact, there is no way that a Bodhisattva either would want to or could delay achieving full enlightenment. As much as the motivation to help others increases, so much closer does one approach Buddhahood.--His Holiness the Dalai Lama, The Dalai Lama at Harvard by of Tibet
