The cause of all causes. Why you have come to this material world? Why you are under the threefold miserable condition of life: adhyātmika, adhibhautika, adhidaivika? These things are to be inquired. "I do not wish to die, but death is forced upon me. I do not want to become old man. Old age is forced upon me." So these are the inquiries, tattva-jijñāsā. But they are not interested, neither educational department nor any other department. They are simply interested, "Where is money? Where is money? Where is money?"
Divā cārthehayā rājan kuṭumba-bharaṇena vā (SB 2.1.3). We are spoiling our night simply by sleeping. And those who have got sex facilities, they enjoying sex life. This is the night's engagement. And day's engagement, "Where is money? Where is money? Where is money?" And if we get money, then how to spend it for relatives, for sons, children. That's all. Divā cārthehayā rājan.
So in this way we shall not spoil our life. The life's purpose is different. They do not know. The modern civilization do not know what is the purpose of life. Na te viduḥ svārtha-gatiṁ hi viṣṇum (SB 7.5.31). They are trying to make adjustment, political situation, social situation in so many problems. The United Nations, they're trying to solve the problems of whole nation, but still the war is going on between such-and-such party, such-and-such party, and everyone busy in politics and diplomacy. This way, the problems of life cannot be solved.
If there is any solution of the problems of life, it is actually this Kṛṣṇa consciousness movement. Those who are intelligent, they should study the purpose of Kṛṣṇa consciousness movement and try to apply in all fields of activities—political, social, religious, anything, economical. Everything can be solved. Jīva . . . jīvasya tattva-jijñāsā. This is called inquiry, inquisitiveness about the Absolute Truth.
Now this verse is describing how one can become interested in the values of life. The values of life is to inquire the Absolute Truth, how this inclination can be developed or how Kṛṣṇa consciousness can be developed. Tattva-jijñāsā means Brahman, Paramātmā and Bhagavān, Kṛṣṇa. Now how this inclination . . .
There is inclination in everyone, but by artificial means they have been checked. Otherwise, normally, this inclination is there in everyone's heart. Nitya-siddha kṛṣṇa-bhakti sādhya kabhu naya (CC Madhya 22.107). It is not an artificial imposition. Naturally there is tendency to know, if he's a sane man, "What I am? What is God? What is my relationship with Him? Why I am suffering?" There are so many questions.
