Final answer:
Communitas is the intense community spirit that develops among individuals sharing rites of passage, characterized by strong social bonds and equality.
Step-by-step explanation:
The intense community spirit that develops from experiencing rites of passage together is known as Communitas. This concept was explored by anthropologist Victor Turner, highlighting the strong sense of equality and social bonding that emerges among participants during these significant transitional periods. In contrast to the more structured and hierarchically organized society, communitas represents a community formed through shared experiences and mutual support during the liminal stage of rites of passage, such as initiation ceremonies or rituals marking adulthood.
