That man is so wrinkled and withering away, and where is his hair? what has happened to him?
I'm perplexed. what is wrong with that old man?
Though Siddhartha had a very comfortable life, he wanted to achieve full spiritual satisfaction. Through fear, Siddhartha's father made sure the city was full of happiness and bliss so his son would not be exposed to the true reality of life beyond the city.
On Siddhartha's first trip he witnessed an old man at the side of the road. Siddhartha was very confused by this as old age was very unfamiliar to him.
"This is a man living the homeless life in order to seek the answer to life's riddle"
What is the meaning of this?
On Siddhartha's second trip, he was puzzled to see an old man lying on the side of the road appearing to not be well. Siddhartha was still yet to fully understand life beyond the city.
I need to live a life of pure moderation
On Siddhartha's third journey, he came across something he was taught was not possible, death. This was a great shock to Siddhartha, as he still was unable to understand the true meaning of what he was seeing.
Someone is in that coffin. Why wouldn't my father tell me about these things?
on Siddhartha's fourth and final journey, he saw a monk and noticed his calm and collected persona. Siddhartha asked the Channa for the meaning of this sighting, and it responded "This is a man living the homeless life in order to seek the answer to life's riddle".
After the Channa gave Siddhartha the key to his vision of the monk, he became inspired by the thought of finding a spiritual solution to the problems in human life, which he perceived as a life of moderation, living in a middle way between both extremes.
