In harmony with the 1st line, the 4th line represents the foundation of the second floor of the house, and builds upon the security that the 1st line creates. There is also a fragility to Line 4 in that it must also allow an opening for the transition into the upper trigram. While Line 3 is deeply involved with material resources, Line 4 is the foundation of transpersonal relationships and concerned with human resources. The 4th line is deeply influential, and waits for opportunities to embrace its community and externalize the foundations, gifts or discoveries of the lower trigram. An innate friendliness, akin to brotherhood or sisterhood, facilitates the 4th line's gift for networking. This friendliness creates the opening needed but also makes 4th lines susceptible to surprise and shock. Their sphere of influence, therefore, is typically limited to people with whom they have already established relationships; strangers are not generally correct for them other than as casual contacts.
Quality of life for 4th lines is in direct proportion to the quality of their network of friends and associates. Establishing their energies in correct relationships allows them to enjoy a genuine camaraderie.1here is also an inflexibility, however, which creates a tendency toward people burnout for the 4th line, and they need times of retreat to nurture and rejuvenate themselves. The potential opportunities that their networks offer must bring a return on the energy investment that they have put into it, or they may abdicate and find a network that does. 4th lines who are living correctly do not create their networks, however; their correct networks are already there and they meet them through Strategy and Authority. The 4th line, having a fixed quality, must transition securely from one network or relationship to another, or lose its security and true opportunities to influence.
"The 4th line is about the human resources of the material plane; people are the biggest decisions and investments they make in their life." —Ra Uru Hu
