Bhagavad Gita 13.20 — Material Nature and the Soul Are Both Beginningless; the Modes and Modifications Arise From Nature

Two Eternal Principles

Lord Krishna says: prakṛtiṁ puruṣaṁ caiva viddhy anādī ubhāv api; vikārāṁś ca guṇāṁś caiva viddhi prakṛtisambhavān—'Know that prakṛti and puruṣa are both without beginning; and know that the modifications and the guṇas are born of prakṛti.'

Until now, Lord Krishna has spoken of the kṣetra (field) and kṣetrajña (knower). Now, using a vocabulary familiar from Sāṅkhya, he restates the same truths in terms of prakṛti and puruṣa, deepening the analysis of how the two relate.

Prakṛti (material nature): This is the source of the field: the body, the senses, the mind and the whole world of matter and subtle matter. It is the creative, ever-changing aspect of reality, the power that brings forms into manifestation.

Puruṣa (the conscious experiencer): This corresponds to the knower, the conscious being who witnesses and experiences. Here the term refers to the living being who experiences the world through the field, a point that will become clearer in the verses that follow.

Anādī ubhāv api (both are beginningless): Neither was created at some point in time. This statement matters because it means the interplay between consciousness and nature has no first moment we can point to. It tells us why the cycle of birth and experience has no known origin, and why spiritual effort is directed not at finding a beginning but at finding a way out. Different schools of Vedānta have understood the exact nature of prakṛti's relationship to the Supreme in different ways, but all agree that, in the context of the living being's experience, the interplay of puruṣa and prakṛti is beginningless.

Vikārāṁś ca guṇāṁś ca prakṛti-sambhavān (modifications and guṇas born of prakṛti): All the changes in the field, such as the body's growth and decay and the mind's moods, and the three guṇas, sattva (clarity), rajas (activity and passion) and tamas (inertia and darkness), arise from prakṛti. This includes the desires, aversions and feelings that we often take to be our deepest selves.

A Liberating Implication

If the modifications and moods are born of prakṛti, then they are not the intrinsic nature of the conscious self. A cloud passing through the sky does not alter the sky itself. When we see our moods, thoughts and desires as products of nature, we gain a gentle distance from them. We can respond to them wisely rather than being swept along.

This verse also sets the stage for verse 22, where Lord Krishna explains how the puruṣa comes to be bound: not by prakṛti itself but by attachment to its guṇas.

Message for Everyday Life (Understanding Where Moods Come From)

Do not take every mood personally: Irritation, laziness and restlessness arise from the play of the guṇas. Knowing this, we can say, 'This is tamas speaking,' or 'This is rajas,' and decide not to act on it blindly.

Support sattva: Since the guṇas are influenced by what we eat, read, watch and do, we can gently shape our daily environment so that clarity and calm have more room to grow.

Practical approach: Each evening, note which guṇa seemed dominant during the day. Without judgment, think of one small step to increase clarity tomorrow, such as an earlier bedtime or less screen time.
