So generally, a human being accepts four principles, namely dharma, artha, kāma, mokṣa (SB 4.8.41, Cc. Ādi 1.90). Dharma means religious principle; artha means economic principle, how to develop economic principle; dharma, kāma, how to satisfy our senses; and mokṣa, and ultimately, salvation. But this is material principles. We have to surpass this material principle, then come to the spiritual platform. That is sarva-dharmān parityajya mām ekaṁ śaraṇam... Sarva-dharmān (BG 18.66). This is also dharma. So just like people are engaged formally. Their temple, church, is sometimes, simply formality. Real, their real business is how to satisfy their senses. "If for satisfying my senses I'll have to pose myself as a religious person, so let me do that." That is their religion. But that is not religion. Real religion is no sense satisfaction, simply to satisfy the Supreme Lord. That is real religion. Therefore (s)he says, bhavān hi veda tat sarvam.
So as somebody, anything, they require four legs... Just like this platform, it has got four legs. Animal stands on four legs. Anything, it requires four pillars. So to remain steadily on the platform of dharma, these four legs required: dharma, artha, kāma... If I simply remain engaged in religious principles and nobody is engaged where to get food... Because food also is required. So therefore not only religious principle, there must be economic development attempt also. But not one-man show. We should divide our society in such a way that somebody, some group of men is engaged in studying the dharma principle and spreading it. Just like we have taken the principle, generally, to spread what is meant by real dharma. That is the business of the brāhmaṇa. And similarly, some group of men should be kṣatriya for ruling over. Unless there is discipline, ruling, everything will be chaos. The government must be there. The principle of directors must be there. So dharma, artha, kāma. And we must live peacefully. Our senses should not disturb us. Because we have got senses, they want satisfaction. So we must give food them also, senses. Dharma, artha, kāma, and mokṣa. But ultimate goal is how to get out of this material existence. This is four principles: dharma, artha, kāma, mokṣa. And mokṣa, by the impersonalists, their mokṣa and real mokṣa... Real mokṣa... Mokṣa means liberation. Liberation means to get out of this material existence.
