Sankaracarya's Vivekachudamani 387

घटकलशकुसूलसूचिमुख्यैः

गगनमुपाधिशतैर्विमुक्तमेकम् ।

भवति न विविधं तथैव शुद्धं

परमहमादिविमुक्तमेकमेव ॥

ghaṭakalaśakusūlasūcimukhyaiḥ

gaganamupādhiśatairvimuktamekam |

bhavati na vividhaṃ tathaiva śuddhaṃ

paramahamādivimuktamekameva ||

(Sankaracarya's Vivekachudamani 387)

Having dropped hundreds of its limitations such as a pot, a pitcher, a barn, or the eye of a needle, space is recognized as one and not as many. So too, the Pure Supreme (Brahman) is indeed one, when freed from the ego and the rest.

Out of many, many thousands of men, one may be interested in how to make perfect this human form of life. And out of many, many thousands of perfect persons, one may know actually what is God, So God is unconquerable, cannot be conquered, or He cannot be understood by your ego and envy mentality. God can be known by the meek and humble who is submissive and who takes the shelter of a God-realized person and tries to hear from him. Such as Sripad Sankaracarya preaching to us by this Vivekachuamani.
