10.3.20

स त्वं त्रिलोकस्थितये स्वमायया बिभर्षि शुक्लं खलु वर्णमात्मन: । सर्गाय रक्तं रजसोपबृंहितं कृष्णं च वणन तमसा जनात्यये ॥ २० ॥

sa tvaṁ tri-loka-sthitaye sva-māyayā bibharṣi śuklaṁ khalu varṇam ātmanaḥ sargāya raktaṁ rajasopabṛṁhitaṁ kṛṣṇaṁ ca varṇaṁ tamasā janātyaye

saḥ tvam
Your Lordship, who are the same person, the Transcendence
tri-loka-sthitaye
to maintain the three worlds, the upper, middle and lower planetary systems
sva-māyayā
by Your personal energy (ātma-māyayā)
bibharṣi
assume
śuklam
the white form of Viṣṇu in goodness
khalu
as well as
varṇam
color
ātmanaḥ
of the same category as You (viṣṇu-tattva)
sargāya
for the creation of the entire world
raktam
the reddish color of rajo-guṇa
rajasā
with the quality of passion
upabṛṁhitam
being charged
kṛṣṇam ca
and the quality of darkness
varṇam
the color
tamasā
which is surrounded by ignorance
jana-atyaye
for the ultimate destruction of the entire creation

My Lord, Your form is transcendental to the three material modes, yet for the maintenance of the three worlds, You assume the white color of Viṣṇu in goodness; for creation, which is surrounded by the quality of passion, You appear reddish; and at the end, when there is a need for annihilation, which is surrounded by ignorance, You appear blackish.
