Why is Siddhartha disillusioned with performing the ritual of ablution?

Siddhartha becomes disillusioned with performing the ritual of ablution because he realizes that such external practices do not lead to true spiritual fulfillment or understanding. He feels that the rituals are mere superficial acts that fail to address the deeper questions of existence and the self. This realization prompts him to seek a more authentic path to enlightenment, one that goes beyond traditional religious practices. Ultimately, Siddhartha is searching for a direct, personal experience of the divine rather than adhering to prescribed rituals.
