Easter in your soul

From The White Witch by
Elizabeth Goudge:

"....she had long accepted the fact
that happiness is like swallows in
Spring. It may come and nest under
your eaves or it may not. You cannot
command it. When you expect to be
happy you are not, when you don't
expect to be happy there's suddenly
Easter in your soul, though it be
midwinter. Something, you don't know
what , has broken the seal upon the door
in the depth of your being that opens
eternity. It is not yet time for you yourself
to go out of it but what is beyond comes
in and passes into you and through you."
