Killing envious demons pleases all saints because it stops the perpetuation of sinful, disturbing activities in the world.Listen — Srila Prabhupada Uvaca
Śrīmad-Bhāgavatam 7.9.13–14 — August 29, 1968, Montreal 680829SB-MONTREAL [43:50 Minutes] Prabhupāda: sarve hy amī vidhi-karās tava sattva-dhāmno brahmādayo vayam iveśa na codvijantaḥ kṣemāya bhūtaya utātma-sukhāya cāsya vikrīḍitaṁ bhagavato rucirāvatāraiḥ [SB 7.9.13] [O my Lord, all the demigods, headed by Lord Brahmā, are sincere servants of Your Lordship, who are situated in a transcendental position. Therefore they are not like us [Prahlāda and his father, the demon Hiraṇyakaśipu]. Your appearance in this fearsome form is Your pastime for Your own pleasure. Such an incarnation is always meant for the protection and improvement of the universe.] So Prahlāda Mahārāja is requesting Lord Nṛsiṁha that "Now You can become peaceful, because the disturbing element, my father, is now finished." So there are two missions when Kṛṣṇa appears, incarnation: paritrāṇāya sādhūnāṁ vināśāya ca duṣkṛtām [Bg. 4.8]. [In order to deliver the pious and to annihilate the miscreants, as well as to reestablish the principles of religion, I advent Myself millennium after millennium.] This material world is a field of activity for the persons who have forgotten Kṛṣṇa.
But there are regulative principles, Vedic knowledge. If we act according to the regulative principle, then we can enjoy. Not actually enjoy, but we think we enjoy. Because in the material world, there is nothing enjoyable for the spirit soul.
Just like a fish: it is an animal of the water. It has nothing to enjoy on the land. So if, by mistake, a fish thinks that "I shall become an elephant and enjoy in the land," that is not possible. Similarly we, spirit soul, ahaṁ brahmāsmi, we are all Brahman, and we have nothing to do with this material world. But because we are Brahman...
Brahman means ānandamaya. Ānanda-cinmaya-rasa [Bs. 5.37]. [I worship Govinda, the primeval Lord, residing in His own realm, Goloka, with Rādhā, resembling His own spiritual figure, the embodiment of the ecstatic potency possessed of the sixty-four artistic activities, in the company of Her confidantes [sakhīs], embodiments of the extensions of Her bodily form, permeated and vitalized by His ever-blissful spiritual rasa.] The Supreme Brahman is sac-cid-ānanda-vigrahaḥ. Īśvaraḥ paramaḥ kṛṣṇaḥ sac-cid-ānanda-vigrahaḥ [Bs. 5.1]. [Kṛṣṇa who is known as Govinda is the Supreme Godhead. He has an eternal blissful spiritual body. He is the origin of all. He has no other origin and He is the prime cause of all causes.] And we are part and parcel of the Supreme Brahman.
Therefore we are also sac-cid-ānanda, eternal, blissful and full of knowledge. But somehow or other, icchā-dveṣa-samutthena [Bg. 7.27]. Icchā-dveṣa-samutthena. [O scion of Bharata [Arjuna], O conqueror of the foe, all living entities are born into delusion, overcome by the dualities of desire and hate.] The real basic principle of our materialistic life is dveṣa. Dveṣa means when we become envious of Kṛṣṇa, that "Why Kṛṣṇa shall be the supreme enjoyer?" In this world, in practical experience, we have seen that many people say that "Kṛṣṇa enjoyed rasa-līlā.
Why we shall not?" So this is..., imitation rasa-līlā is going on in this material world, but they cannot be satisfied, because it is imitation. Just like if a female takes the part of a male and wants to imitate the enjoyment, it is simply false. Similarly, we are constitutionally female, enjoyed, prakṛti. In the Bhagavad-gītā it is said, apareyam itas tu viddhi me prakṛtiṁ parā jīva-bhūtaṁ mahā-bāho [Bg. 7.5]. [Besides this inferior nature, O mighty-armed Arjuna, there is a superior energy of Mine, which are all living entities who are struggling with material nature and are sustaining the universe.] Prakṛti means female, enjoyed. So jīva is described in the Bhagavad-gītā as prakṛti.
The first prakṛti is the material elements, eight. bhūmir āpo 'nalo vāyuḥ khaṁ buddhir mano eva ca aparā... prakṛti me bhinnā aṣṭadhā [Bg. 7.4] [Earth, water, fire, air, ether, mind, intelligence and false ego-altogether these eight comprise My separated material energies.] These are separated energy. But apareyam, they are inferior. Apareyam itas tu anyā parā. Besides this material nature, this dull matter, there is another nature: prakṛti, parā prakṛti, the jīva.
