Know nature and even the Person [to be] beginningless, both, indeed.
And know manifestations and even qualities to arise from nature.

Source: Milind S. Pandit

Know that Prakriti and Purusha are both beginningless; and also know that all manifestations and Gunas arise from the Prakriti.

Source: The Bhagavad-Gita: The Sacred Song

Material nature and the living entities should be understood to be beginningless. Their transformations and the modes of matter are products of material nature.
