Robertson Work, a Buddhist and author of several books states this position clearly: "If Buddhists focus on cultivating compassion just within themselves, they are not being Bodhisattvas. A compassionate being who understands the truth of interbeing and impermanence is motivated to liberate other beings from delusion and suffering. Bodhisattvas, as engaged Buddhists, must take part in political, social, economic, cultural, and environmental actions that relieve suffering. This includes engagement at various levels—family, community, city, state, nation, international, and planetary. Of course, this is an impossible mission but we have always known that the vows to relieve all suffering are such. However, we continue to make this vow and take every action that we can within our spheres of influence."
