From Krishna, the Topmost Yoga System, by His Divine Grace A.C. Bhaktivedanta Swami Prabhupada
The transcendental vibration established by the chanting of Hare Krsna, Hare Krsna, Krsna Krsna, Hare Hare/ Hare Rama, Hare Rama, Rama Rama, Hare Hare, is the sublime method for reviving our transcendental consciousness As living spiritual souls, we are all originally Krsna conscious entities, but due to our association with matter from time immemorial, our consciousness is now adulterated by the material atmosphere. The material atmosphere, in which we are now living, is called maya, or illusion. Maya means that which is not. And what is this illusion? The illusion is that we are all trying to be lords of material nature, while actually we are under the grip of her stringent laws. When a servant artificially tries to imitate the all-powerful master, it is called illusion. We are trying to exploit the resources of material nature, but actually we are becoming more and more entangled in her complexities. Therefore, although we are engaged in a hard struggle to conquer nature, we are ever more dependent on her. This illusory struggle against material nature can be stopped at once by revival of our eternal Krsna consciousness. Hare Krsna, Hare Krsna, Krsna Krsna, Hare Hare is the transcendental process for reviving this original pure consciousness. By chanting this transcendental vibration, we can cleanse away all misgivings within our hearts. The basic principle of all such misgivings is the false consciousness that I am the lord of all I survey.
Krsna consciousness is not an artificial imposition on the mind. This consciousness is the original natural energy of the living entity. When we hear the transcendental vibration, this consciousness is revived. This simplest method of meditation is recommended for this age. By practical experience also, one can perceive that by chanting this maha-mantra, or the Great Chanting for Deliverance, one can at once feel a transcendental ecstasy coming through from the spiritual stratum. In the material concept of life we are busy in the matter of sense gratification as if we were in the lower animal stage. A little elevated from this status of sense gratification, one is engaged in mental speculation for the purpose of getting out of the material clutches. A little elevated from this speculative status, when one is intelligent enough, one tries to find out the supreme cause of all causes — within and without. And when one is factually on the plane of spiritual understanding, surpassing the stages of sense, mind and intelligence, he is then on the transcendental plane. This chanting of the Hare Krsna mantra is enacted from the spiritual platform, and thus this sound vibration surpasses all lower strata of consciousness — namely sensual, mental and intellectual. There is no need, therefore, to understand the language of the mantra, nor is there any need for mental speculation nor any intellectual adjustment for chanting this maha-mantra. It is automatic, from the spiritual platform, and as such, anyone can take part in vibrating this transcendental sound without any previous qualification. In a more advanced stage, of course, one is not expected to commit offenses on grounds of spiritual understanding.
In the beginning, there may not be the presence of all transcendental ecstasies, which are eight in number. These are: (1) Being stopped as though dumb, (2) perspiration, (3) standing up of hairs on the body, (4) dislocation of voice, (5) trembling, (6) fading of the body, (7) crying in ecstasy, and (8) trance. But there is no doubt that chanting for a while takes one immediately to the spiritual platform, and one shows the first symptom of this in the urge to dance along with the chanting of the mantra. We have seen this practically. Even a child can take part in the chanting and dancing. Of course, for one who is too entangled in material life, it takes a little more time to come to the standard point, but even such a materially engrossed man is raised to the spiritual platform very quickly. When it is chanted by a pure devotee of the Lord in love, it has the greatest efficacy on hearers, and as such this chanting should be heard from the lips of a pure devotee of the Lord, so that immediate effects can be achieved. As far as possible, chanting from the lips of nondevotees should be avoided. Milk touched by the lips of a serpent has poisonous effects.
The word Hara is the form of addressing the energy of the Lord, and the words Krsna and Rama are forms of addressing the Lord Himself. Both Krsna and Rama mean the supreme pleasure, and Hara is the supreme pleasure energy of the Lord, changed to Hare (Hah-ray) in the vocative. The supreme pleasure energy of the Lord helps us to reach the Lord. The material energy, called maya, is also one of the multi-energies of the Lord. And we the living entities are also the energy, marginal energy, of the Lord. The living entities are described as superior to material energy. When the superior energy is in contact with the inferior energy, an incompatible situation arises; but when the superior marginal energy is in contact with the superior energy, called Hara, it is established in its happy, normal condition.
These three words, namely Hara, Krsna and Rama, are the transcendental seeds of the maha-mantra. The chanting is a spiritual call for the Lord and His energy, to give protection to the conditioned soul. This chanting is exactly like the genuine cry of a child for its mother’s presence. Mother Hara helps the devotee achieve the Lord Father’s grace, and the Lord reveals Himself to the devotee who chants this mantra sincerely. No other means of spiritual realization is as effective in this age of quarrel and hypocrisy as the maha-mantra: Hare Krsna, Hare Krsna, Krsna Krsna, Hare Hare/ Hare Rama, Hare Rama, Rama Rama, Hare Hare.
