Devotional service is not within these material qualities. They are transcendental. Bhakti is transcendental. Therefore, you cannot understand Kṛṣṇa, or God, without bhakti. Bhaktyā māṁ abhijānāti (BG 18.55). Only bhaktyā māṁ abhijānāti. Otherwise, it is not possible. Bhaktyā māṁ abhijānāti yāvan yas cāsmi tattvataḥ. Reality, in reality, if you want to understand what is God, then you have to adopt this bhakti process, devotional service. Then you transcend. Therefore, in the Śrīmad Bhāgavatam Nārada says that tyaktvā sva-dharmaṁ caraṇāmbujaṁ harer (SB 1.5.17). If anyone, even by sentiment, gives such . . . gives up his occupational duty according to guṇa . . . that is called svadharma. Svadharma means one's duty according to the quality he has acquired. That is called svadharma. The brāhmaṇa, kṣatriya, vaiśya, śūdra, they are divided, guṇa-karma-vibhāgaśaḥ (BG 4.13), by guṇa and karma.
So here Arjuna says that kārpaṇya-doṣopahataḥ-svabhāvaḥ (BG 2.7). "I am kṣatriya." He understands that, "I am doing wrong. I am refusing to fight. Therefore, it is kārpaṇya-doṣa, miserly." Miserly means I have got some means to spend, but if I don't spend, this is called miser. Kṛpaṇatā. So kṛpaṇatā. There are two classes of men: brāhmaṇa and śūdra. Brāhmaṇa and śūdra. Brāhmaṇa means he's not miser. He has got the opportunity, great asset of this human form of body, many millions of dollars' worth, this human . . . but he's not using it properly, simply seeing it: "How beautiful I am." That's all. Just spend your beauty or utilize your asset, the human . . . that is brāhmaṇa, to be liberal.
