just my opinion but the last  line  is saying that these colours via the meaning of the colours is “how the bird moves” so to speak

ashvaghosha's view is fundamentally solipsistic , again in my opinion

i have a different interpretation of the significance of the colours, red is a unity of infinity and reality and the most potent and personally crucifying of the colours, though there can be a certain benignness to it

blue is sort of like a high energy coupling of infinity, dangerous and manic and only taking infinity in this high energy way

gold is new to me and i have yet to work it out, probably some illusory safe area!

white i usually take to be a sexually charged colour !

it's

so

unusual

to

come

across

any

interest

in

colours

like

this

and

to

see

it

walk

out

from

1900

years

ago

like

this

is

almost

unbelievable !
