As long as one's aptitude is sufficient, by following routine procedures, practicing a Dao-level technique similar to 'Primordial Spirit Nirvana Skill', and integrating all learned knowledge, choosing an auspicious day, sensing the heart's call, one can knock open the Celestial Gate.
However, the Celestial Gate is a Divine Soul Inner Realm, linked with Heaven and Earth, producing a mystical state.
In ancient times, this step was referred to as constructing 'Heaven and Earth Two Bridges', stepping into it meant merging with Heaven and Earth, thus reaching a level where one can fly and escape the earth, borrowing the natural law.
Whether the Celestial Gate can transform from illusion to reality not only depends on personal accumulation and whether the cultivation is complete but also relies on the feedback and reflection of Heaven and Earth.
If one does not receive the recognition of Heaven and nature.
