Sitting: Sitting is a state of practice, which means sitting and falling.
This realm of practice belongs to worldly dharma. It is a stage that can be experienced in many practices: such as Taoism, Zen, and yoga. It is not Buddhism. Monks can do it, Taoists can do it, esoteric practitioners can do it, and even intellectuals outside the teachings can do it after training. Of course, Buddhist monks can do it too.
The foundation of this method lies in the separation of the spirit and the physical body, and achieving voluntary control. For example, in yoga, during the practice, by visualizing the three chakras, seven chakras, and the bright point, you can control the bright point to pop out from the top of the central channel to sit dead.
After practicing to a certain level, a small pore will appear at the top of the central channel. However, during practice, sometimes due to poor control, the soul may accidentally pop out of the central channel and sit down unexpectedly. Therefore, Taoist masters often insert a grass root on the top of the head to block the central channel.
It is worth mentioning that being able to sit down does not mean you have enlightenment. Many people, such as some Taoist priests, have escaped life and death through this method, and even play freely in the six paths of reincarnation, but they still cannot achieve enlightenment and become Buddhas.
Feathering: The word "feathering" in traditional Chinese mythology comes from Taoism. Most people have heard of ascending to immortality by becoming immortals. In fact, becoming immortals refers to a very short period of time before the ascension period of a monk. During this period, the practitioner himself is very fragile. Practitioners who have just experienced the inner demon tribulation have almost zero ability to respond to changes in the outside world at this time. But once the emergence is over, it is the ascension period that all ascetics dream of. The emergence can also be said to be the last hurdle to become an immortal.
Honghua: Venerable Wushouguang once pointed out in "Treasures of Judgment and Meaning" that top yogis who study Tantra should have four forms of achievement, namely:
(1): Achievement without any remaining dust.
(2): In order to save others, it is accomplished with the light body of the rainbow filling the sky.
(3): The light body disappears into the void and is achieved.
(4): Achieved by the physical body disappearing directly into the void.
These achievements are actually Honghua.
