Nanda was the the stepsister of Prince Siddhattha (who years later became the Buddha), the daughter of his father King Suddhodana and his adoptive mother Queen Maha Pajapati Gotami (the sister of Siddhattha's biological mother).
Sundari Nanda's vision: Beauty fades quickly with time lapse magic.
Ailing, impure, and putrid,
Develop the meditation on the foul,
Make the mind unified, well composed.
As is this so was that,
As is that so this will be [cause and effect],
Putrid, exhaling a foul odor,
A thing in which fools delight.
Inspecting it as it is,
Unwearying by day and night,
With my own wisdom I pierced right through,
And so saw for myself.
As I dwelled ever heedful,
Dissecting it with methodical attention
[parsing the body into its contituent parts with the mind],
I saw this body as it really is,
Both inside and outside, internal and external.
Then I became disenchanted with this body,
My inward attachment faded away.
Being diligent and detached at heart,
I live in peace, fully quenched.”
