Ūrdhva-mūlam adhah-śākham aśvatthaṁ prāhur avyayam (BG 15.1). Avyayam, eternal. This material energy also eternal. There are three kinds of energies of the Supreme Personality of Godhead: the material energy, the spiritual energy and the marginal energy. From the material energy, bhūmir āpo 'nalo vāyuḥ, this material creation is effected. And the spiritual energy, the Vaikuṇṭha-loka, paras tasmāt tu bhāvaḥ anyaḥ avyaktaḥ avyaktāt sanātanaḥ (BG 8.20), that is eternal. So that is spiritual world. And in between the two worlds, material and spiritual, there is one energy. That is living energy. We living entities, we are marginal energy. We are also energy. Apareyam itas tu viddhi me prakṛtiṁ parām, jīva-bhūtāṁ mahā-bāho yayedaṁ dhāryate jagat (BG 7.5). Kṛṣṇa describes the marginal energy, the jīva-bhūta, the living entities.
So jīva-bhūta, living entities, they are actually prakṛti, not puruṣa. Puruṣa is Supreme Personality of Godhead. Puruṣa means enjoyer. But Māyāvādī philosophy, they want to turn the prakṛti into puruṣa. The jīva, jīva is described as prakṛti, parā-prakṛti. Jīva-bhūta. They are better than, superior than the matter because they adjust matter. The resources, the material resources, they try to enjoy it. They cannot enjoy, but try to enjoy it. Therefore it is called superior energy. But it is energy, not the energetic.
