[The calling of spirits is one of the powers supposed to be possessed
by disciples of the Old Philosopher (Taoists), who reach a high
state of spiritual attainment. While the natural desires remain
they cloud and obstruct spiritual vision; once rid of them, even
angels and immortal beings become unfolded to the sight. They say,
"If once all the obstructions of the flesh are eliminated even God
can be seen." They also say, "If I have no selfish desire, the night
around me will shine with golden light; and if all injurious thoughts
are truly put away, the wild deer of the mountain will come down and
play beside me."
Ha Sa-gong, a Taoist of high attainment, as an old man used to go
out fishing, when the pigeons would settle in flights upon his head
and shoulders. On his return one day he told his wife that they were
so many that they bothered him. "Why not catch one of them?" said his
wife. "Catch one?" said he. "What would you do with it?" "Why, eat it,
of course." So on the second day Ha went out with this intent in heart,
but no birds came near or alighted on him. All kept a safe distance
high up in mid-air, with doubt and suspicion evident in their flying.]
