Men's Group

When a boy was initiated and then became an adult, joining in the membership of the elder males, there has always been some sort of challenge to overcome. Through this challenge, the young man (boy) was forced to confront his fears and overcome them. Such challenges would reinforce the importance of learning the basic skills and ethics that would enable them to be successful adults and to gain the confidence needed to navigate the similar challenges facing them in the future.
In joining the "men's group", their connections, their dependence and the loyalty to the larger society would be reinforced in a tacit or explicit contract. The new promoted man would then be controlled to some degree by this new membership --and without such a thing, the male energy can be instead diverted in ways that are less healthy to the man himself and the society as a whole.

I think society needs to replace this kind of ritual entry into adulthood through some forms of ritual if we are to better channel male energy.

"Ritual has three specific characteristics. First, it occurs in a unique social space, set apart from everyday life. Second, communication operates through symbols and emotions rather than relying primarily on words or rational thought. In ritual, individuals learn by doing and utilize nonverbal communication. Third, ritual confirms and transforms people's worldviews, identities, and relationships with others."
