Each stage in the cultivation process has its own specific achievement mark. For example, if you successfully build the foundation, you can become a human immortal, if you refine your qi and transform into a god, you can become an earthly immortal, and if you refine your god and turn it into a void, you can become a heavenly immortal. However, successful cultivation requires four major conditions: Dharma (cultivation theory), wealth (material support), companions (fellow practitioners), and land (suitable cultivation environment). Only by meeting these conditions can one effectively cultivate the indestructible true body, instead of relying solely on the physical body. The four major false combinations are earth, water, wind, and fire, which represent the composition of the physical body, and the real pursuit is to cultivate the eternal Dharma body.
