2520. That it is mutual love wherein [is] all felicity, and that heaven consists in mutual love and everyone regarding himself as nothing; besides other things which belong to love may be evident from those things that [are] in nature, from atmospheric parts, from the parts and viscera in the human body, where there is nothing given that does not possess something of health from the general [principle] because it contributes to the general [principle]; thus there is a confluence of the felicity of all into them who do not strive for themselves, but for the general [good] in faith, and the contrary [happens] to those who strive for themselves, and wish that they maybe instead of themselves in the place of others who are much worthier. - 1748, July 4.
