Claim. The Kingdom of Heaven is not entered through external conditions or eschatological events but begins from the resolved heart of the individual who unites mind and body — Jesus’ “the Kingdom is within you” reread as a beginning, not a denial of the external Kingdom.
Elaboration. SMM treats Jesus’ saying as the starting condition rather than the whole answer: “Jesus’ disciples did not understand the reality of his teaching. In working to prepare a foundation of happiness for the coming Kingdom of Heaven, they had self-centered concerns for their position. Seeing this, Jesus fundamentally demolished this fallacy and taught that the Kingdom was in one’s heart” (1.1. The location of the Kingdom of Heaven, 46-21, 1971.7.18). “God’s Kingdom begins from our resolution and determination to open up an environment for our body to unite with such a mind. Where the actions of the mind and body are separated, the Kingdom does not exist. Advancement towards the Kingdom begins where the mind and body are united.” The internal kingdom is necessary but not sufficient; the external substantial kingdom must follow from minds and bodies in unity.
