In contemporary terms, being spiritual means being connected to one's inner spirit in a way that does not rely on the traditional forms that were around in the West for several millennia. For many, this post-traditional view of spiritual life is bound up with many of the uncertainties that the scientific and technological advances of the 20th century threw up, notably the invention of nuclear weaponry. In the West, this certainly had an impact on the hippy generation of the late 1960s and early 1970s, many of whom dabbled in psychedelic drugs and found that their inner selves – their spirits, if you will – were expanded by their trips. Into this mix came New Age beliefs which tended to focus more on spiritual lives than materialistic ones. Furthermore, certain folk beliefs started to make a revival around the same time as interest in Druidism and Paganism began to alter how many people viewed their spiritual lives.
