We chant Hare Krishna as the highest glorification of God.
Why is that?
It is because we are following in the footprints of Lord Caitanya Mahaprabhu who only chanted the the Hare Krishna Maha mantra even though He also said there are millions of names of God you can also chant.
Srila Prabhupad explains as follows-
Srila Prabhupada - "Lord Caitanya Mahāprabhu says that God has millions and billions of names, so any name is as good as "Kṛṣṇa," it doesn't matter".
Devotee - "So Srila Prabhupada, then why do we concentrate on just chanting the Hare Kṛṣṇa Maha Mantra?"
Srila Prabhupada - "Because we are following in the footprints of Lord Caitanya and who only chanted these holy names -
Hare Krishna Hare Krishna
Krishna Krishna Hare Hare
Hare Rama Hare Rama
Rama Rama Hare Hare
So this is why we are chanting this "Hare Krsna Maha Mantra", therefore we request you most humbly, there is no loss on your part, but the gain is immense. If you take to this chanting of Hare Kṛṣṇa, then gradually your misconception of this life will be cleared off.
You will understand your real identity and you will act in that way. And the technology is so nice that you may remain in your business, that doesn't matter.
Simply you have to chant Hare Kṛṣṇa. Suppose you are walking on the street. If you chant Hare Kṛṣṇa, nobody is taxing you, nobody is bothering you. But if by chanting Hare Kṛṣṇa, if you derive some benefit, why do you neglect it? That is our submission". (Lecture to Technology Students M.I.T. - Boston - May 05, 1968)
Of all mantras in the Vedas, one is called the maha-mantra, or great mantra:
Hare Krishna, Hare Krishna
Krishna Krishna, Hare Hare
Hare Rama, Hare Rama
Rama Rama, Hare Hare.
The simple translation of this Maha Mantra is -
''Oh my Lord, Oh energies of the Lord, please my Lord engage me eternally in your devotional service''.
harinama harinama harinama eva kevalam
kalau nastyeva nastyeva nastyeva gatir anyatha
“‘In this Age of Kali there is no other means, no other means, no other means for self-realization than chanting the holy name, chanting the holy name, chanting the holy name of Lord Hari.’
In this age of Kali-yuga, chanting the mahā-mantra is the best way to get out of this Material World
Hare Kṛṣṇa Hare Kṛṣṇa,
Kṛṣṇa Kṛṣṇa Hare Hare,
Hare Rāma Hare Rāma,
Rāma Rāma Hare Hare
Srila Prabhupada - ''Kṛṣṇa consciousness is not an artificial imposition on the mind. This consciousness is the original energy of the living entity.
When we hear the transcendental vibration, this consciousness is revived. And the process is recommended by authorities for this age.
This chanting of
Hare Kṛṣṇa, Hare Kṛṣṇa,
Kṛṣṇa Kṛṣṇa, Hare Hare/
Hare Rāma, Hare Rāma,
Rāma Rāma, Hare Hare,
is directly enacted from the spiritual platform, surpassing all lower states of consciousness-namely sensual, mental and intellectual.
There is no need of understanding the language of the mantra, nor is there any need of mental speculation nor any intellectual adjustment for chanting this mahā-mantra.
It springs automatically from the spiritual platform, and as such, anyone can take part in this transcendental sound vibration, without any previous qualification, and dance in ecstasy.
We have seen it practically, even a child can take part in the chanting, or even a dog can take part in it.
The chanting should be heard, further, from the lips of a pure devotee of the Lord, so that immediate effect can be achieved.
As far as possible, chanting from the lips of a nondevotee should be avoided, as much as milk touched by the lips of a serpent causes poisonous effect.
The word Harā is a form of addressing the energy of the Lord. Both Kṛṣṇa and Rāma are forms of addressing directly the Lord, and they mean "the highest pleasure, eternal."
Harā is the supreme pleasure potency of the Lord. This potency, when addressed as Hare, helps us in reaching the Supreme Lord.
The chanting is exactly like a genuine cry by the child for the mother. Mother Harā helps in achieving the grace of the supreme father, Hari, or Kṛṣṇa, and the Lord reveals Himself to such a sincere devotee.
No other means, therefore, of spiritual realization is as effective in this age, as chanting the mahā-mantra,
Hare Kṛṣṇa Hare Kṛṣṇa,
Kṛṣṇa Kṛṣṇa Hare Hare,
Hare Rāma Hare Rāma,
Rāma Rāma Hare Hare
Srila Prabhupada - ''When the superior energy is in contact with inferior energy, it becomes an incompatible situation. But when the supreme marginal potency is in contact with the spiritual potency, Harā, it becomes the happy, normal condition of the living entity''. (Purport to Hare Krsna Mantra The Happening Record Album 1966 New York City USA)
What is the best way to understand all these millions of temporary material universes (Brahmanda's) that all originate from the Body of Maha Vishnu, along with all the material bodily containers or vessels the soul (jivatma) is in and possesses?
Such material compartments or vessels the soul is in, also originate from the dreaming Body of Maha Vishnu.
The soul or jivatma is covered by these perishable material bodies allowing the soul to exist embodied temporarily in the material creation.
All souls enter the material creation from Vaikuntha (And not the impersonal Brahman as the less intelligent impersonal yogis believe)
They then take shelter as an individual unit within the Body of Maha Vishnu until He spreads them throughout His vast universes, giving such rebellious fallen souls suitable material bodily containers so they can experience their mistaken material bodies.
No souls originate from the Maha Vishnu, it is foolishness to believe souls originate from Him.
Maha Vishnu does however, provide ALL material bodily vessels to the souls who choose to enter the material creation.
Srila Prabhupada tells us sadly about 10% of jiva souls in Vaikuntha and Goloka Vrindavana do CHOOSE to leave the Spiritual Worlds and enter the temporary material universe of repeated birth and death.
This happens because all material bodily vessels eventually break down and wear out forcing the jiva soul to take another material vessel from Maha Vishnu to continue the search of for filled material desires.
Remember that Maha Vishnu provides all material bodies to the jiva souls who ENTER there material creation and absolutely no jiva souls originate from Him.
This decaying troublesome material creation is always in a constant struggle inflicted with repeated birth and death.
This material creation is NOT and NEVER was the jiva souls real home to begin with!
Nothing living originates from the dead material creation, all life enters the material world ORIGINALLY from Vaikuntha or Goloka Vrindavana as explained above.
Srila Prabhupada - ''When the superior energy is in contact with inferior energy, it becomes an incompatible situation. But when the supreme marginal potency is in contact with the spiritual potency, Harā, it becomes the happy, normal condition of the living entity''.
The "Happening Album" New York City 1966 USA
We should not try and make ourselves comfortable in these perishable troublesome decaying material bodily vessels!
Our only desire should be to get out of this decaying temporary decomposing place and go back home back to Godhead, back to the eternal youthfulness of our full potential and who we really are as an eternal youthful person (jiva soul) in Vaikuntha and Goloka Vrindavan.
We should not allow the material energy to trick us either and NOT desire to go to higher material heavenly planets or build comfortable Cities, Sky Scrappers and opulant housing on this world.
We also should not attempt to seek higher birth in a rich aristocratic family in the material world foolishly thinking such a birth will bring satisfaction, peace and happiness in this mundane world.
Such attempts to enjoy this mundane material world is really trying to build the Kingdom of God without God foolishly thinking we ARE the material vessel we occupy even though we see it decaying before our very eyes.
Such an attempt of permanent happiness is not possible in this material creation that is eternally in a state of decay, decline and inflicted with repeated birth and death.
We should all learn we are the individual jiva soul trapped within these temporary outer changing material bodily containers we are in.
Along with the illusion and silly belief that we will not die, even though people are dying around us all the time, is the sad delusion we are the material body when in fact we are NOT the material bodily container we are in.
We must seriously try to understand that all material endevours in search for happyness in this world will fail!
And will never NOT solve the problems of repeated birth, disease, old age and death.
So GET OUT OF THIS MATERIAL CREATION and "Get Back" to where you belong!
