5266. 'And the seven heads of grain are seven years' means a state when truth within the exterior natural is multiplied. This is clear from the meaning of 'heads of grain' in the good sense as factual knowledge, dealt with in 5212, and therefore as the truths known to the exterior natural, for Such truths are called facts; and from the meaning of 'years' as states, dealt with immediately above in 5265, where the meaning of 'seven' may also be seen.
