One is gradually purified if one cultivates knowledge, even through mental speculation, and strictly follows the regulative principles enjoined in the Å›Ästras and explained in the next verse. Therefore the platform of jñÄna, speculative knowledge, is better than the platform of karma, fruitive action. There is every chance of falling from the platform of karma to hellish conditions, but on the platform of jñÄna one is saved from hellish life, although one is still not completely free from infection. The difficulty is that on the platform of jñÄna one thinks that he has been liberated and has become NÄrÄyaṇa, or BhagavÄn. This is another phase of ignorance.

(BhÄg. 10.2.32)
Because of ignorance, one speculatively thinks himself liberated from material contamination although actually he is not. Therefore even if one rises to brahma jñÄna, understanding of Brahman, one nevertheless falls down because of not taking shelter of the lotus feet of Kṛṣṇa. Nonetheless, jñÄnÄ«s at least know what is sinful and what is pious, and they very cautiously act according to the injunctions of the Å›Ästras.
