“Heaven and earth are only three feet apart, but in thin places that distance is even shorter.” – Celtic saying
In the Celtic mind there were ‘thin places’ and ‘thin times’ – places in the world and times of the year when the distance between heaven and earth grew smaller.
This is consistent with the Jewish interpretation of certain places (Jerusalem, Bethel) being holy or sacred, and times of the year (the appointed times) when God visits His people.
