“I vow to save all beings”, or as it is also said “I vow to be with all things” is to the vow that the bodhisattva takes to put others before one’s self. Of all the precepts if you were to just observe that vow completely, the rest of the vows and precepts could dissolve into that one because you would be just looking out for the welfare of others, not based on your opinion but based on perception. You perceive an apparent other and at the same time, if you are training your mind, you will also perceive reality as it actually is.
