Printing: the man holds four fingers in his left hand (the woman holds four fingers in her left hand). Because the man's left hand is yang and the woman's right hand is yang, so the yang hand lives outside and the yin hand lives inside), and the right hand holds the left thumb (the woman holds the left hand and the right thumb). At the same time, the big fingertips of both hands touch the Laogong point of the other palm (the depression in the middle of the palm) respectively.

Function and explanation: Sitting quietly with both hands to seal, which is called "Dantian Seal" in Taoist circles. "The seal on the abdomen" means that the position of the seal is in our abdomen area. The two fingers below the navel are wide inward, that is, the abdomen, which is the "fine fu-organs" and ends here. Generally, it is "Tai Chi Seal", or "Tai Chi Formula" or "Tai Chi Yin Yang Eight Diagrams Chain Formula". When this handprint is formed, the thumb of both hands forms the shape of "Taiji diagram" at the tiger's mouth, and the big finger is in the palm of the other hand, which is the two eyes of Taiji diagram, used to connect one's yin and yang. The other four fingers represent "gossip", with one yin and one yang in both hands, so it is called "Taiji Yin and Yang gossip chain tactics". So the yang hand protects the yin hand, and the yin hand holds the yang hand. This is the Tao.

The meaning of "negative yin holding yang" in Yijing.

Hands folded, just like connecting the positive and negative poles of the power supply, yin and yang are naturally connected. Moreover, after the combination of yin and yang, a closed aura will be formed immediately, and the mood will naturally calm down, and the hands will soon feel hot and swollen, which is wonderful. Such a natural peace of mind, natural thought stop, natural body peace and natural qi movement have incredible effects on meditation practice.
