Licking on a bottle of honey

Source: BG 2.12 Purport

Those who are envious of Kṛṣṇa as the Supreme Personality of Godhead have no bona fide access to the great literature. The non-devotee’s approach to the teachings of the Gītā is something like that of a bee licking on a bottle of honey. One cannot have a taste of honey unless one opens the bottle. Similarly, the mysticism of the Bhagavad-gītā can be understood only by devotees, and no one else can taste it, as it is stated in the Fourth Chapter of the book. Nor can the Gītā be touched by persons who envy the very existence of the Lord. Therefore, the Māyāvādī explanation of the Gītā is a most misleading presentation of the whole truth. Lord Caitanya has forbidden us to read commentations made by the Māyāvādīs and warns that one who takes to such an understanding of the Māyāvādī philosophy loses all power to understand the real mystery of the Gītā.
