What is the “ferry to God’s kingdom”?  Can it be seen?

The phrase “ferry to God’s kingdom” is a parable.  Actually,

it refers to Tien-Tao, which cannot be seen.  Why would it take on

the name “ferry to God’s kingdom”?  It is because humans are in the

sea of sufferings.  When humans are alive, they are lost.  After they die,

they are tried in the Underworld.  Then they take one of the six paths in

the cycle of birth, death and rebirth.  As this perpetuates, they sow a

variety of causes and receive a variety of effects, like riding endless

tides and waves in the ocean.  They cannot find a way to escape, and

suffer through the cycle of birth, death and rebirth in great pain.  Isn’t

this the sea of sufferings?  However, if a person becomes a practitioner

of Tao, he treats the physical world as an imaginary flower, fame and

wealth as dreams, and his wife and children as emotional burdens. 

He understands that all matters and phenomena cannot endure, and

upon their destruction, their existence becomes nil; the true existence

is in the Void, for the Void is eternal.  Thus, he has no struggle nor

obstacle in his way.  Isn’t this the same as if he has boarded the ferry

to God’s kingdom?
