The Experience of the Change can uproot both Ignorance & Egoism!
At Savatthi the blessed Buddha said:
Bhikkhus, when the perception of impermanence is developed and cultivated, then
it eliminates all sense desire, it also eliminates all lust for becoming something else,
it also eliminates all ignorance and it finally uproots this deep conceit that 'I Am'...
Just as, bhikkhus, in the autumn, when the sky is clear & cloudless, the rising sun
dispels all darkness from the space as it shines, beams and radiates, so too when
the perception of impermanence is developed and cultivated, then it eliminates all
sense desire, it eliminates all lust for becoming something else, & it also eliminates
all ignorance. Finally it even uproots this core conceit that 'I Am'...!!!
And how, bhikkhus, is perception of impermanence developed & cultivated so that
it eliminates all sense desire, so that it eliminates lust for becoming something else,
so that it eliminates ignorance & so that it finally uproots the conceit that 'I Am'??
Such is this form, such is the origin of form, such is the passing away of form...
Such is feeling, such is the origin of feeling, such is the passing away of feeling...
Such is perception, such is the origin of perception, such is its passing away ...
Such is mental construction, such is the origin of construction, & its passing away...
Such is consciousness, such is the origin of consciousness, such is its passing away...
That is how the perception of impermanence is developed and cultivated so that it
eliminates all sense desire, so that it eliminates all lust for becoming something else,
so that it eliminates all ignorance & so that it finally uproots this conceit 'I Am'...!!!

Causes of origin cause emergence when present, while ceasing when they are absent:
The Body is caused by Food, Ignorance, Lust for Form, and Intention resulting in Form.
Cause of Feeling is Contact, Ignorance, Lust for Feeling, & Intention resulting in Feeling.
Cause of Perception is Contact, Ignorance, Lust for Perception, & Intention resulting in
Perception. Cause of Construction is Contact, past Ignorance, Lust for Construction, and
Intention resulting in Construction. The Cause of Consciousness is mentality-&-materiality,
prior Ignorance, Lust for mentality-&-materiality, and Intention resulting in Consciousness!
Ignorance is not knowing Suffering, Cause of Suffering, End of Suffering & the Noble Way
to End Suffering...
Whether going above, across or back again, wherever he goes in this world
let him carefully scrutinize the arising & ceasing of all constructed things...
