Buddha found enlightenment by going off on his own after sitting under the Bodhi tree, Yeshua became enlightened after his time alone in the wilderness...
So why would people presume by being a loyal sheep, one day they will become a shepherd?
I'm not a fan of following anyone as it usually means blind obedience, parroting your mentor and living his life. Inspiration is better, being inspired by various people and things and using them for your own progress. Still the path would be your own.
The question is what enlightenment is and whether once can see the truth and achieve wisdom. In most religions, complete enlightenment is possible only after death. After the pilgrimage of life, death is the final initiation. If one believes in reincarnation, then this process takes much longer.
I recall a certain story I read while I was young. It went like this:
One man desired to see the Truth. Every day he went to the temple of the goddess, Athena, and prayed for enlightenment. One day when he was lying prostrate on the ground embracing the feet of the goddess, he noticed that the statue became alive and started moving. Athena laid her hand on his shoulder and promised to show him the Truth. She took him up the high mountain to the Temple where the Truth dwelled. It was the light covered by ten veils. The goddess told the man that each day he was allowed to tear off one veil. The more veils the man tore off the brighter the light became and the more clearly he could see the Truth.
Finally, only one veil remained and the goddess warned the man that it would be better if it remained in place. But the man was so hungry for wisdom and so curious that he tore off the last veil and in that moment he became blind. He could only hear Athena laughing and saying "You fool, how could you think a mere mortal man can see the Truth without any veils?"
Perhaps, enlightenment is nothing else than realization of one's ignorance. Didn't Socrates say: "I know that I know nothing." Everything we see is filtered through our senses that are imperfect and misleading, our experience, which makes us subjective, our prejudices and ego defenses. Do we even know what enlightenment is? There are so many interpretations. What is wisdom? What is truth? Can they be defined? If not, then how can anyone say they are enlightened or wise?
