SB 2.4.9
yatha gunams tu prakrter
yugapat kramaso ’pi va
bibharti bhurisas tv ekah
kurvan karmani janmabhih
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The Supreme Personality of Godhead is one, whether He alone acts with the modes of material nature, or simultaneously expands in many forms, or expands consecutively to direct the modes of nature.
