Refining Emptiness - The Path to Oneness with the Dao

"Refining Emptiness to Unite with the Dao" in Neidan is the supreme practice of Daoist internal alchemy cultivation. The so-called "refining emptiness to unite with the Dao" also embodies the reverse thinking and the concept of "breaking attachments" in Daoism. From refining essence into qi, to refining qi into spirit, and then from refining qi into spirit to refining spirit to return to emptiness, all follow the thinking mode of regression and restoration.
Daoism holds that when entering the state of emptiness, if there is a clinging mind, it indicates that one has not yet escaped the "active" methods. One should further eliminate the clinging mind, even forgetting emptiness itself without any traces, so as to finally merge into one with the authentic Great Dao.

From the Zhong-Lü Daoist lineage in the Tang Dynasty to all Daoist alchemists in the Ming and Qing dynasties, they have repeatedly emphasized the spirit of "refining emptiness to unite with the Dao". As one of the "Seven Perfected Ones" of the Quanzhen Dao, Qiu Chuji clearly explained this inThe Direct Pointing of the Great Elixir, while Li Daochun referred to it as "breaking through emptiness". The most basic idea of "breaking through emptiness" is to forget all clinging minds to active practices, enabling the self to transcend both the object and the self itself.

Refining Emptiness - The Path to Oneness with the Dao

Liàn Xū Hé Dào

In the profound tradition of Daoist internal alchemy (内丹术, Nèidānshù), the stage of Refining Emptiness to Merge with Dao (炼虚合道) represents the culmination of spiritual cultivation - the complete union of individual consciousness with the primordial Dao. This transcendent practice is the final stage of the alchemical journey, where the practitioner becomes one with the ultimate reality.

Following the stages of Refining Essence into Qi (炼精化气), Refining Qi into Spirit (炼气化神), and Refining Spirit to Return to Emptiness (炼神还虚), this ultimate transformation represents the return to the source of all existence. Ancient texts describe this as "the immortal merges with the great Dao" - the complete transcendence of all dualities.
