Let me be clear, although there’s way to know for certain, I’m confident the average person using gang signs on a regular basis is not doing it for spiritual or energy enhancing purposes.
More than likely they are being used solely for communication and identification purposes.
At this point, ‘gang signs’ are associated with criminal organizations and criminal activity. The negative elements of the hand gestures are usually always attached to the inner city melanated youth (and adults) who choose to communicate or identify themselves with a specific set of hand postures and motions.
It wasn’t always this way though. In fact, in other contexts what most consider as ‘gang signs’ are used by spiritualist, ancient and modern, to “facilitate the flow of energy in the subtle body and enhance one’s journey within“.
According to Wikipedia, “A mudra is a symbolic or ritual gesture or pose in Hinduism, Jainism and Buddhism. While some mudras involve the entire body, most are performed with the hands and fingers. As well as being spiritual gestures employed in the iconography and spiritual practice of Indian religions, mudras have meaning in many forms of Indian dance, and yoga. The range of mudras used in each field (and religion) differs, but with some overlap. In addition, many of the Buddhist mudras are used outside South Asia, and have developed different local forms elsewhere.”

As any ‘curious melanated mind’ should know by now, most if not all of the spiritual practices found in the world can be traced back to the original man and woman, the black (melanated) man and woman. More specifically, the indigenous African man and woman. Especially Hinduism, Jainism and Buddhism.
In fact, history proves beyond a shadow of a doubt that Buddha has African origins.
In other words, it’s no coincidence that the melanated minds who are most often perceived as gang members or associated with “gangs” unconsciously integrated an ancient indigenous spiritual practice within our modern culture.
It’s too bad that most of the melanated minds who subscribe to “gang culture” have no idea that their hand gestures could be used to stimulate blood flow, harness energy, and tap into spiritual power. You never know though, maybe they are already benefiting from this practice but don’t even recognize it. Like the saying goes, “Knowledge is power”.
