Devotee: What determines, Śrīla Prabhupāda, if one is serious or one is not serious? What makes one...
Prabhupāda: Well, this seriousness comes after many, many births. It is also not so easy. Rūpa Gosvāmī says, tatra laulyam api mūlyam ekalaṁ janma-koṭi-sukṛtair na labhyate. He wrote a verse, kṛṣṇa-bhakti-rasa-bhāvitā matiḥ krīyatāṁ yadi kuto 'pi labhyate: "The kṛṣṇa-bhakti, Kṛṣṇa consciousness, this thing, if you can purchase somewhere, just immediately purchase it." Kṛṣṇa-bhakti-rasa-bhāvitā matiḥ krīyatām: "Just purchase." Yadi kuto 'pi labhyate. First of all, if you want to purchase, the things must be available. Yadi kuto. Therefore kuto 'pi, "If it is available, immediately purchase." Then next question is, "What is the value? What is the price I have to pay?" Then he said, tatra laulyam ekalaṁ mūlyam, "Simply your serious eagerness to have it. That is the price." "Oh, that I can have very easily." "No." Janma-koṭi-sukṛtair na labhyate: "That laulyam, that seriousness, is not obtained after thousands of years' pious activities." It is so difficult. Janma-koṭi-sukṛtair na labhyate.
