Bringing Salvation to the Three Worlds
Tien-Tao brings salvation to the Three Worlds: mankind, souls of the deceased in the Underworld, and deities in the spiritual world. This special mission of Tien-Tao is very difficult to comprehend. Bringing salvation to mankind is similar to goals of other religions. Due to the change of spiritual forces in the cosmos, the Enlightened Teacher with the Heavenly Decree is descended and the door to Tien-Tao is wide open; therefore anyone may have the opportunity to obtain Tien-Tao if he wishes.
In regard to bringing salvation to the souls of the deceased in the Underworld, we may learn from the legends of Monk Mu-lian rescued his mother and Princess Miao-shan rescued her father from Hell as described in Buddhist Sutras. Tien-Tao has brought salvation to innumerous souls of the deceased who came to Godís Altar with Immortals or Buddhas through Fu-luan (Fu-luan is also known as Sand Writing or Planchette writing)
However, bringing salvation to the deities in the spiritual world was never heard before. In human history, we have only learned that the deities will bring salvation to mankind, but not otherwise. During this Last Catastrophe in the Third Period, the spiritual world will destruct totally; hence salvation must be brought to the deities.
If a soul in the spiritual world wishes to ascend to the Heaven of Truth, he must devote a long period of practice or wait for a suitable opportunity. A suitable opportunity, for example, is when Tien-Tao is made accessible to all souls. Once he received Tien-Tao, he ascends to Heaven of Truth. It is easier but longer to practise in Heaven; more difficult but shorter to practise in the Human world. Therefore, one good deed in the human world is worth more than thousands of good deeds in Heaven. Now that the Final Catastrophe is near, the spiritual world will also destruct. Some deities in the spiritual world are not afraid to be dragged into seven emotions and six desires in the human world so they risk themselves to be born in this world to receive Tien-Tao. Those deities who do not wish to risk themselves in the human world may search for their relatives or friends in previous lives to be their Introducers and Guarantors of Tao to help them to ascend to Li-tien (Heaven of Truth).
After receiving Tien-Tao, the deities can descend to Godís Altar to depict the Truth through Fu-luan. They will also clearly express their relationships with the Introducers and Guarantors of Tao in previous lives. This can be evidenced by lots of written lectures done by these deities through Fu-luan.
