The three teachings all emphasized different things and all gave different method of achieving certain thing
The Dao have the principle of "Seeing the Dao with one own eyes"
One could learn and one must forget, those who could not learn and could not forget, could not see.
Hence "the Dao that can be spoken of is not the eternal Dao"
The Dao is nature, I am nature, and thus I attain the Dao, seeking nothing outside. Then you could see
And when one could see one could not help but say "This is fate"
Daoist always emphasize the word "destiny"
With destiny, one can perceive Dao at a glance, without it, even a lifetime of study would be like an outsider trying to peer inside.
Those enlightened one is opposite. Dao is concealment within manifestation, while those enlightened one's method is manifestation within secrecy
What one seeks, they do not conceal.
They display it openly.
