Great compassion and skilful means (directed toward liberation) are conditions for the perfections. Skilful means is the wisdom which transforms giving (and the other nine perfections) into requisites for awakening. Through wisdom a bodhisattva brings him or herself across (the stream of suffering), through compassion he or she leads others across. Through wisdom one understands the suffering of others, through compassion one strives to alleviate their suffering. Through wisdom one destroys all attachments, but because of compassion, one never desists from activity that benefits others. Through wisdom one is free from "I-making" and "mine-making," through compassion one is free from lethargy and depression. Through wisdom and compassion one becomes one's own protector and the protector of others.
