So daytime's engagement and night's engagement is finished, then where is the engagement for ātma-tattvaṁ? Where is the engagement for understanding self-realization? This is the difference between gṛhamedhī and gṛhastha. A gṛhastha means he may live, just like here we see Śrī Caitanya Mahāprabhu, Śrī Nityānanda Prabhu, Śrī Advaita Prabhu and Gadādhara Prabhu and Śrīvāsa Prabhu, they are all gṛhasthas, family men, but their business was different—to cultivate self-realization. Not that divā cārthehayā rājan kuṭumba-bharaṇena vā. So the difference between gṛhasthas and gṛhamedhīs is like this. A gṛhastha is living a regulative life on principles to understand self-realization, and a gṛhamedhī, who has no vision, no idea of the aim of life . . . (break)
. . . that the gṛhamedhīs, they are sleeping. So for their good, He took sannyāsa, renounced order of life. This brāhmaṇa, kṣatriya, vaiśya, śūdra, the brahmacārī, gṛhastha, vānaprastha, they are for mutual cooperation. They are different department, but they are for mutual cooperation. As I have already explained several times, just like in my body there are different departments—these eight departments—the arm department, the belly department and the leg department. Similarly, the human society also be divided into departments. The brain department means the brāhmaṇa and the sannyāsa, the brain department. And the arms department means the kṣatriya and the gṛhasthas. And the belly department is the vaiśyas and vānaprastha;, and the leg department, the śūdras and the brahmacārīs, two legs. This is the scientific division of human society.
But unfortunately, at the present moment, they are not interested. They do not know how to divide the human society in four material order and four spiritual order. Of course there is some order, division. Just like still there is a class of men who are very intelligent—philosophers, scientists, or poets, or writers and thinkers, thoughtful. There is a class of men still. And there is a class of men who are interested taking part in politics, in administration, in diplomacy. And there is a class of men, they are interested in business, industry, trade. And there is a class of men, means less intelligent; they cannot take part in any these. They can serve somewhere and get some bread, that's all. So there are these four classes of divisions, but not in an organized way—topsy-turvy way. Therefore we find so many discrepancies in spite of economic development, education advancement.
