See-saw

Heaven, happiness, keys to the kingdom, the kingdom and its many mansions all refer to the heart, the body, and its many parts and particles

Heaven, happiness, keys to the kingdom, the kingdom and its many mansions all also refer to the universe, the planets and its many parts and resources

Heaven, happiness, keys to the kingdom, the kingdom and its many mansions all refer to the hell that conditions the mind to create emotional upheaval of happiness

It is possible to step from heaven and step in to hell; step from hell and step in to heaven as quickly and easily as it is to breath in and out, consciously or unconsciously while going to and fro on the swing of life
