At the present moment, the Kali-yuga, the śāstra says, almost everyone is a śūdra because nobody can live independently. Kalau śūdra-sambhavaḥ. Kalau means in this age, this iron age, almost everyone is a śūdra. It is very difficult to find out really brāhmin, kṣatriya. Vaiśyas maybe there are, but mostly śūdras. Because the other three orders of life are missing, therefore at the present moment there is no peace. In every step there is fight, there is quarrel. Kali means disagreement and quarrel.
So this age is called Kali-yuga. This Kali-yuga has begun since the Battle of Kurukṣetra. You have heard in Mahābhārata or in the Bhagavad-gītā. Bhagavad-gītā is within Mahābhārata. The Battle of Kurukṣetra between the two section of cousin-brothers, the Kauravas and the Pāṇḍavas, took place under the guidance of Lord Śrī Kṛṣṇa five thousand years ago. And in that battlefield, Kṛṣṇa instructed Arjuna, His friend, the great book of knowledge, Śrīmad Bhagavad-gītā. So human life must be divided into four orders, varṇāśrama-dharma. In the Viṣṇu Purāṇa it is said:
- varṇāśramācāravatā
- puruṣeṇa paraḥ pumān
- viṣṇur ārādhyate panthā
- nānyat tat-toṣa-kāraṇam
- (CC Madhya 8.58)
The aim of human life is to understand God. That is the main business of human life. Main . . . na te viduḥ svārtha-gatiṁ hi viṣṇum (SB 7.5.31). Viṣṇu is the Supreme Lord, Supreme Personality of Godhead. People, they do not know what is the ultimate goal of life. The ultimate goal of life is to understand the Lord, the Supreme Lord, Viṣṇu. Viṣṇu means "all-pervading God." God is not localized. God is all-pervading. Just like it is stated in the Brahma-saṁhitā:
- eko 'py asau racayituṁ jagad-aṇḍa-koṭiṁ
- yac-chaktir asti jagad-aṇḍa-cayā yad-antaḥ
- aṇḍāntara-stha-paramāṇu-cayāntara-sthaṁ
- govindam ādi-puruṣaṁ tam ahaṁ bhajāmi
- (Bs. 5.35)
