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."
