Those interested in materialistic activities remain in the cycle of birth and death. Pravṛtti-mārga, or the inclination to stay in the material world to enjoy varieties of sense gratification, has been explained in the previous verse. Now, in this verse, it is explained that one who has perfect brahminical knowledge rejects the process of elevation to higher planets and accepts nivṛtti-mārga; in other words, he prepares himself to go back home, back to Godhead. Those who are not brāhmaṇas but atheists do not know what is pravṛtti-mārga or nivṛtti-mārga; they simply want to obtain pleasure at any cost. Our Kṛṣṇa consciousness movement is therefore training devotees to give up the pravṛtti-mārga and accept the nivṛtti-mārga in order to return home, back to Godhead. This is a little difficult to understand, but it is very easy if one takes to Kṛṣṇa consciousness seriously and tries to understand Kṛṣṇa. A Kṛṣṇa conscious person can understand that performing yajña according to the karma-kāṇḍa system is a useless waste of time and that merely giving up the karma-kāṇḍa and accepting the process of speculation is also unfruitful. Therefore Narottama dāsa Ṭhākura has sung in his prema-bhakti-candrikā:
- karma-kāṇḍa, jñāna-kāṇḍa, kevala viṣera bhāṇḍa
- 'amṛta' baliyā yebā khāya
- nānā yoni sadā phire, kadarya bhakṣaṇa kare,
- tāra janma adhaḥ-pāte yāya
A life of karma-kāṇḍa or jñāna-kāṇḍa is like a poison pot, and one who takes to such a life is doomed. In the karma-kāṇḍa system, one is destined to accept birth and death again and again. Similarly, with jñāna-kāṇḍa one falls down again to this material world. Only worship of the Supreme Person offers one the safety of going back home, back to Godhead.
