Everything is there. Here you require the sunlight, the moonlight, the electricity, but there is another nature, paras tasmāt tu bhāvaḥ anyo 'vyakto 'vyaktāt sanātanaḥ (BG 8.20). There, there is no need of sun, there is no need of moon, because each and every planet is illuminating. Yad gatvā na nivartante. And if you go there, then you do not come back again in this material world, which is duḥkhālayam aśāśvatam, nāpnuvanti mahātmānaḥ saṁsiddhiṁ paramāṁ gatāḥ (BG 8.15).
So our aim should be how to go back to home, back to Godhead. But we do not know. We are simply acting like cats and dogs, that's all. Jumping like dog, cat, and eating, sleeping, and having sex intercourse and trying to defend my position. These things are done by the animals. These things are done by animals. Then what is your benefit you get, this human form of life? Śāstra says:
- tapo divyaṁ putrakā yena sattvaṁ
- śuddhyed yasmād brahma-saukhyaṁ tv anantam
- nāyaṁ deho deha-bhājāṁ nṛloke
- kaṣṭān kāmān arhate viḍ-bhujāṁ ye
- (SB 5.5.1)
"This human form of life is not meant for working very hard like cats and dogs. It is meant for tapasya. Tapasya: simple life, and realize yourself. And then you stop the miserable condition of your life. Tapo divyaṁ yena śuddhyet sattvam."
"Just like when we are diseased, we go to the physician and we try to cure the disease; similarly, we do not know what is our main disease. That is explained by Kṛṣṇa previously. Janma-mṛtyu-jarā-vyādhi (BG 13.9)—this is our real disease, to take birth, to die, to become old and to become victims of disease. But nobody knows how to cure this, and still, we are very much proud of becoming advanced in education and civilization. This is called illusion. This is called illusion. The real disease is how to stop janma-mṛtyu."
"Kṛṣṇa has repeatedly said, tyaktvā dehaṁ punar janma naiti mām eti kaunteya. Janma karma me divyaṁ yo jānāti tattvataḥ (BG 4.9): "Simply try to understand Me, Kṛṣṇa. The result will be tyaktvā deham . . ." That is . . . after giving up this body we have to accept another body. Kṛṣṇa says: "Simply if you understand Me in truth, then thereafter, no more accepting any material body. You remain in your spiritual body and come to the spiritual world, back to home, back to Godhead."
So here, prakṛtiṁ puruṣaṁ caiva. Although prakṛti is also Kṛṣṇa's nature, bhūmir āpo 'nalo vāyuḥ khaṁ mano buddhiḥ (BG 7.4), He said apareyam: "This is inferior nature." So apareyam itas tu viddhi me prakṛtiṁ parām: "Another superior nature there is." What is that? Jīva-bhūtaḥ, this living entity. So we are also prakṛti, and the material nature is also prakṛti. It is inferior prakṛti, and we are superior prakṛti. As we are now under the control of this inferior prakṛti, we can transfer ourself under the control of the superior prakṛti.
That superior prakṛti is spiritual world. This material world means it is made of this inferior prakṛti, bhūmir āpo 'nalo vāyuḥ. And there is another prakṛti, sanātana. That is stated in the Bhagavad-gītā; you'll find in the Eighth Chapter: paras tasmāt tu bhāvaḥ anyaḥ (BG 8.20). Bhāva means nature. Avyakto 'vyaktāt sanātanaḥ. Sanātanaḥ means that is not destroyed. And this prakṛti is destroyed. Bhūtvā bhūtvā pralīyate (BG 8.19). So bhūtvā bhūtvā pralīyate means that prakṛti is fact, but the manifestation is temporary. It is not false.
Just like you become sometimes angry, so you show some symptom. That symptom is within you, but it is manifested sometimes; sometimes it is not manifested. But the propensity, the quality of your becoming angry, is there eternally. It is not that it is created. Anything. Sometimes you become passionate. To become passionate is there, it is not a new thing, but it sometimes appears, sometimes disappears. Similarly, this material world . . . this is also prakṛti of Kṛṣṇa. The fact is that it is sometimes manifest, sometimes not manifest. Just like the cloud. Cloud is a fact, but sometimes it is manifest; sometimes it is not manifested. When it is not manifest, you cannot say: "Cloud is false." No. It is a fact, but the nature is sometimes manifest, sometimes not manifest. So here Kṛṣṇa says, prakṛtiṁ puruṣaṁ caiva viddhy anādī. They are eternal. Kṛṣṇa is eternal, and the living entities are eternal, and the prakṛtis are also eternal. They are not false, but they are manifested, sometimes not manifested.
