Why can't handprints in Buddhism be tied casually?
It is a secret method of stealing Buddha's fingerprints, which has no inheritance and recognition. Not only can you not print your fingerprints privately without initiation, but even all the secrets of the Tripitaka should not be read or learned privately according to Buddhist precepts. However, with the development of information today, many people make Tantric handprints into tapes, videos, CDs and DVDs for sale, or put them on the Internet, which is unfair.

The main method of body secret is to "knot fingerprints". Simply put, it is the practice of crossing hands and fingers and combining imagination to form different shapes. There are thousands of tantric handprints, each of which has a special meaning and function, such as: auspicious seal, King Kong Dahui seal, big wheel altar seal, magic seal, Bao Guan Bao Bao seal, light fireworks seal, bound thinking seal, quasi-nine-headed dragon seal and so on. Although some handprints have the same name, their shapes are quite different.
For example, the seal of King Kong armor is a kind of demon-seeking protection (for example, if you imagine it as an armor with a clear seal, you will burn a flame on yourself and the disgusting demon will fly away). Ninja nine seals are: exclusive seal, Daikin steel wheel seal, external lion seal, internal lion seal, external binding seal, internal binding seal, knowledge seal, Japanese wheel seal and invisible seal.
As far as Dongmi is concerned, it can produce the effect of blessing practitioners through the combination of ten fingers and the idea of psychological imagination, which conforms to certain practice and forms different "handprints" with each other.
Besides handprints, there are all kinds of sitting postures, which are as diverse and meaningful as handprints. Auspicious meditation and devil meditation are two kinds of meditation that ninjas often practice. Ninja usually needs to cooperate with the "incense" in the Five Classics of Ninja (detailed in later chapters) to practice the spirit of auspicious sitting and devil sitting.
