How do you step from the top of a 100-foot pole?

How do you step from the top of a 100-foot pole? This is an ancient Zen koan. A what?!? A Zen Koan is a story or parable that is used in the practice of Zen Buddhism. Koans form part of larger stories meant for contemplation and meditation. Koans are passed down through various Buddhist teachers. When meditating on a koan, it is said that it can help one arrive at a more enlightened mental state, helping one arrive closer to the ultimate Buddhist goal of Nirvana. They present puzzles or questions that cannot be solved through rational thought.
The story that entails the koan goes as follows:

Master Sekiso said, "You are at the top of the 100 foot high pole. How will you make a step further?" Another Zen Master of Ancient Times said, "One who sits on top of the 100 foot pole has not quite attained true enlightenment. Make another step forward from the top of the pole and throw one's own body into the 100,000 universes."

Should there be any who is able to step forward from the top of the 100 foot pole and hurl one's whole body into the entire universe, this person may call oneself a Buddha. Nevertheless, how can one step forward from the top of the 100 foot pole? Know thyself!

Should one be content and settle on top of the 100 foot pole,
One will harm the third eye,
And will even misread the marks on the scale.
Should one throw oneself and be able to renounce one's life,
Like one blind person leading all other blind persons,
One will be in absolute freedom (unattached from the eyes).

What I have derived from this is that stepping from a 100-foot pole is a metaphor for having trust in one's self and the only way to fully trust one's self is to know one's self. To know one’s self, one must have reached an enlightened state of mind because knowing one’s self fully does not rest solely on knowing trivial things such as what you like or dislike. It has to do with being at peace, letting go of all desires, all material objects, all negative energy that keeps us at the top of the pole. Once we know ourselves truly, our minds will be open to all levels of life and true joy will commence!
