…The best and ultimate authority is Kṛṣṇa, for He is our eternal well-wisher, and He always speaks for our benefit. Since we have to accept some authority, why not accept His? Simply by hearing of His glories from Bhagavad-gītā and Śrīmad-Bhāgavatam and by chanting His names: Hare Kṛṣṇa, Hare Krsna, Krsna Krsna, Hare Hare, Hare Rama, Hare Rama, Rama Rama, Hare Hare, we can swiftly perfect our lives.
Kṛṣṇa Consciousness, the Matchless Gift

Spiritual Knowledge Through Kṛṣṇa
The aim of this Kṛṣṇa consciousness movement is to bring all living entities back to their original consciousness. All living entities within the material world are, to varying degrees, afflicted with a type of madness. This Kṛṣṇa consciousness movement aims at curing man of his material disease and reestablishing his original consciousness. In a Bengali poem a great Vaiṣṇava poet has written, “When a man is haunted by ghosts, he can only speak nonsense. Similarly, anyone who is under the influence of material nature should be considered haunted, and whatever he speaks should be considered nonsense.” One may be considered a great philosopher or great scientist, but if he is haunted by the ghost of māyā, illusion, whatever he theorizes and whatever he speaks is more or less nonsensical. Today we are given the example of a psychiatrist who, when requested to examine a murderer, proclaimed that since all the patients with whom he had come in contact were more or less crazy, the court could excuse the murderer on those grounds if it so desired. The point is that in the material world it is very difficult to find a sane living entity. The prevailing atmosphere of insanity in this world is all caused by the infection of material consciousness.
The purpose of this Hare Kṛṣṇa movement is to bring man back to his original consciousness, which is Kṛṣṇa consciousness, clear consciousness. When water falls from the clouds, it is uncontaminated like distilled water, but as soon as it touches the ground it becomes muddy and discolored. Similarly, we are originally pure spirit soul, part and parcel of Kṛṣṇa, and therefore our original constitutional position is as pure as God’s. In Bhagavad-gītā Sri Kṛṣṇa says:
