Originally, mystical experiences were very general and abstract but it had no names. The reality of mysticism was in almost everybody, hence it needed no names. Gradually with the rise of society, people gave it a name such as astrology, spirituality etc. and started to create gods and idols from these derivative and placeholder abstract concepts. The high priest or the kings of those cultures started to assume the role of gods for the rest of the people. With advancement of civilization, people started to add rigor to these subjective and authoritarian spirituality and renamed it a organized religion. Unfortunately, those religions themselves became even more authoritarian and dogmatic than ever before. With the advent of modernity people tried to add further rigor to this religion (rigor being empiricism) with some unrealistic and futile rigor called "Science". Originally it had no name, it only had the reality. Now it has only names such as Hinduism, Buddhism, Christianity, Judaism, Islam, New Age, but they hardly have any residual reality anymore. It's the human nature to corrupt and degenerate whatever good was handed down to them. Over time, everything is reduced to some fancy names with no intrinsic value [nominalism], and the underlying reality is lost, with few exceptions. 

Originally Sufism did not have a name but they had the true reality. This is not entirely true because it had a name, the name being Islam. All the close companions of the prophet, all the builders of magnificent mosque, were themselves Sufi without any separate names. Now, Islam along with Sufism have names but its loosing it's reality, with few exceptions. 

Every early original scientists had the true essence of reality with them but they did not have any separate names. They were just regarded as "wise men" or Sages. With the advent of a name called "scientist" in 19th century [To be exact 1833 AD, not BC!], the scientists have lost their reality and now they have just its names and dogmas, with few exceptions. 

During early parts of your life, you felt the true essence in your guts but at that time it had no names. You felt the divine essence without any name or any proof. But soon you trained yourself in wrong hands, believed in those untrue premises as unquestionable and started to give those divine sparkle a name like "enlightenment". Soon thereafter, you are chasing this unreal ghost named "enlightenment". There are no enlightenment to achieve and conquer in first place. Whatever is there, it’s always there, and there is no additional need to hunt for it. Now the essence of enlightenment is gone and only the word enlightenment remains. This is how your life's reality is lost and only its name remains, again with few exceptions.
