From the perspective of the way in which Buddhist teachings investigate, elucidate, diagnose, treat, and cultivate the life-and-world, this paper provides a definition of “caring about life” through philosophical analysis and reasoning, and then comes up with some guidelines for how to care about life appropriately. This paper is divided into six sections. Section one offers a broad outline of this paper’s argument and a breakdown of its individual sections. Section two seeks to clarify the meaning of the phrase “caring about life.” Section three critically reflects on how caring about life is both relevant to and significant for either living in the world or inquiring into the life-and-world. Section four lays out four guidelines for how to care about life in an appropriate and consistent manner. Taking Bodhisattva practices as an illustration, section five demonstrates that caring about all sentient beings can be broadly and thoroughly actualized by way of incessant cultivation and salvation. Section six concludes and summarizes the main points of this paper.
