Defined in the Gītā

Knowledge

What is knowledge?

Humility, pridelessness, nonviolence, tolerance, simplicity, approaching a bona fide spiritual master, cleanliness, steadiness and self-control; renunciation of the objects of sense gratification, absence of false ego, the perception of the evil of birth, death, old age and disease; nonattachment to children, wife, home and the rest, and evenmindedness amid pleasant and unpleasant events; constant and unalloyed devotion to Me, resorting to solitary places, detachment from the general mass of people; accepting the importance of self-realization, and philosophical search for the Absolute Truth—all these I thus declare to be knowledge, and what is contrary to these is ignorance.

Bhagavad-gītā 13.8–12

See the definition

Purport

The Lord has described in summary the body, knowledge and the knowable. This knowledge is of three things: the knower, the knowable and the process of knowing. Combined, these are called vijñānam, or the science of knowledge. Perfect knowledge can be understood by the unalloyed devotees of the Lord directly. Others are unable to understand. The monists say that at the ultimate stage these three items become one, but the devotees do not accept this. Knowledge and development of knowledge mean understanding oneself in Kṛṣṇa consciousness. We are being led by material consciousness, but as soon as we transfer all consciousness to Kṛṣṇa's activities and realize that Kṛṣṇa is everything, then we attain real knowledge. In other words, knowledge is nothing but the preliminary stage of understanding devotional service perfectly.
