The fifth and final yama is aparigraha and means non-possessiveness or non-greed. This can be thought of as holding on to things too tightly, not sharing. There is also an element of how this relates to others. Are you giving people gifts with the expectation of future good treatment?
We see this in politics… look at how people are often “gifted” cars, trips, private jet rides, with the expectation of landing a contract?! This is not a true gift!
