They are the pleasure potency of the Supreme Personality of Godhead. The Supreme Personality of Godhead cannot have a material wife or a material companion. Kṛṣṇa's Rādhārāṇī or Lord Rāmacandra's Sītādevī, Nārāyaṇa's Lakṣmīdevī, they are pleasure potency of the Supreme Personality of Godhead. Rādhā kṛṣṇa-praṇaya-vikṛtir hlādinī śaktir asmāt (CC Adi 1.5). Āhlādinī-śakti. Kṛṣṇa, God, has got many potencies. One of the potencies is called āhlādinī-śakti, pleasure potency. So Kṛṣṇa's consort, Lord Rāmacandra's consort, they are pleasure potency, exhibited.
So to show the example, Lord Rāmacandra, because Sītā was kidnapped, Sītā was insulted, or Rāmacandra was insulted, the retaliation was Lord Rāmacandra killed not only Rāvaṇa but the whole dynasty, finished. Only for one woman. He could create so many. No. Because ātatāyinaḥ, aggressed over. Just to teach people that anyone, if he is aggressor, he must be killed. This is the position.
But Arjuna is considering whether it will be pious or impious. This is devatā. In every action they will consider, "What I am going to do, whether it is pious or impious." That is devatā, "If it is pious, then it will elevate me. And if it is impious, then it will degrade me." Nobody wants degradation. The human life should be especially meant for elevation, not for degradation. You have come to this human form of life from the lower status of life. Jalajā nava-lakṣāṇi sthavarā lakṣa-viṁśati kṛmayo rudra-saṅkhyakāḥ (Padma Purāṇa).
Through so many status of life: the aquatics, the trees, the plants, the insects, the reptiles, the birds, the beasts. In this way . . . bahūnāṁ janmanām ante. Bahūnāṁ sambhavante (BG 7.19). This human form of life is gotten, we have received, after many, many births. These people, they do not know. It is very rare.
Therefore Narottama dāsa Ṭhākura sings, manuṣya janama pāiya, rādhā-kṛṣṇa nā bhajiyā, jāniyā suniyā viṣa khāinu (Hari hari viphale). Hari hari viphale janama goiṅu. He is lamenting, "My dear Kṛṣṇa, I am so unfortunate. I got this human form of life. It was meant for developing Kṛṣṇa consciousness. But I have wasted my time otherwise. So how it is so?" Jāniyā suniyā viṣa khāinu, "Knowingly I have taken poison. Knowingly." Labdhvā sudurlabhaṁ idam bahu-sambhavante, manuṣyam artha-dam (SB 11.9.29).
Manuṣyam . . . these people, they do not know. Because they are asuras, they do not know what to do in this human form of life and what not to do. They are killing animals without any hesitation. They do not know, these rascals. And still they are spiritual leaders. How horrible condition is this, in this Kali-yuga, just imagine. Without any restriction, without any hindrance, they are committing sinful life. They do not know, next life, all this boastfulness, pride, will be finished. He will have to accept another body, which will be offered by the material nature. You cannot say that, "I will not accept this body; I want this body." No. Nature is not under your dictation. You have to abide by the dictation of nature. Prakṛteḥ kriyamāṇāni. This verse of Bhagavad-gītā is very important.
