have already performed yajnas, etc

 
Śukadeva Gosvāmī especially stresses that it is already concluded that one who has come to the stage of chanting the Hare Kṛṣṇa mantra with determination and steadiness must be considered to have already passed the trials
The importance of chanting Hare Krsna, Hare Krsna, Krsna Krsna, Hare Hare/ Hare Rama, Hare Rama, Rama Rama, Hare Hare is very strongly stressed in the Second Canto, 1st Chapter, 11th verse, of the Srimad-Bhagavatam in the following way: Sukadeva Gosvami tells Maharaj Pariksit: "My dear King, if one is spontaneously attached to the chanting of the Hare Krsna maha-mantra, it is to be understood that he has attained the highest perfectional stage." It is specifically mentioned that the karmis who are aspiring after the fruitive results of their activities, the salvationists who are aspiring to become one with the Supreme Person, and the yogis who are aspiring after mystic perfections can achieve the results of all perfectional stages simply by chanting the maha-mantra. Sukadeva uses the word nirnitam, which means "it is already decided." He was a liberated soul and therefore could not accept anything which was not conclusive. So Sukadeva Gosvami especially stresses that it is already concluded that one who has come to the stage of chanting the Hare Krsna mantra with determination and steadiness must be considered as having already passed the trials of fruitive activities, mental speculation and mystic yoga.    (More...)
The same thing is confirmed in the Adi Purana by Krsna. While addressing Arjuna He says, "Anyone who is engaged in chanting My transcendental name must be considered to be always associating with Me. And I may tell you frankly that for such a devotee I become easily purchased."    (More...)
In the Padma Purana also it is stated: "The chanting of the Hare Krsna mantra is present only on the lips of a person who has for many births worshiped Vasudeva." It is further said in the Padma Purana: "There is no difference between the holy name of the Lord and the Lord Himself. As such, the holy name is as perfect as the Lord Himself in fullness, purity and eternity. The holy name is no material sound vibration, nor has it any material contamination." The holy name cannot, therefore, be chanted offenselessly by one who has failed to purify his senses. In other words, materialistic senses cannot properly chant the holy names of the Hare Krsna maha-mantra. But, by adopting this chanting process, one is given a chance to actually purify himself so that he may very soon chant offenselessly.    (More...)

As it is stated in the previous verse, a person who has once offenselessly chanted the holy name of God becomes immediately eligible to perform Vedic sacrifices. One should not be astonished by this statement of Srimad-Bhagavatam. One should not disbelieve or think, "How by chanting the holy name of the Lord can one become a holy man to be compared with the most elevated brahmana?" To eradicate such doubts in the minds of unbelievers, this verse affirms that the stage of chanting of the holy name of the Lord is not sudden, but that the chanters have already performed all kinds of Vedic rituals and sacrifices. It is not very astounding because no one in this life can chant the holy name of the Lord unless he has passed all lower stages, such as performing the Vedic ritualistic sacrifices, studying the Vedas and practicing good behavior like that of the Aryans. All this must first have been done. Just as a student in a law class is to be understood to have already graduated from general education, so anyone who is engaged in the chanting of the holy name of the Lord, Hare Krsna, Hare Krsna, Krsna Krsna, Hare Hare/ Hare Rama, Hare Rama, Rama Rama, Hare Hare, must have already passed all lower stages. It is said that those who simply chant the holy name with the tip of the tongue are glorious. One does not even have to chant the holy name and understand the whole procedure, namely the offensive stage, offenseless stage and pure stage; if the holy name is sounded on the tip of the tongue, that is also sufficient. It is said herein that nama, a singular number, one name, Krsna or Rama, is sufficient. It is not that one has to chant all the holy names of the Lord. The holy names of the Lord are innumerable, and one does not have to chant all the names to prove that he has already undergone all the processes of Vedic ritualistic ceremonies. If one chants once only, it is to be understood that he has already passed all the examinations, not to speak of those who are chanting always, twenty-four hours a day. It is specifically said here, tubhyam: "unto You only." One must chant God's name, not, as the Mayavadi philosophers say, any name, such as a demigod's name or the names of God's energies. Only the holy name of the Supreme Lord will be effective. Anyone who compares the holy name of the Supreme Lord to the names of the demigods is called pasanḍi, or an offender.    (More...)

In Srimad-Bhagavatam [3.33.7] it is also stated that even if a person is born in a family of canḍalas-the lowest birth one can get in human society-he is glorious if he chants the holy names of the Lord, for it is to be understood that by such chanting a devotee definitely proves that he underwent all kinds of austerities in his previous life. By the grace of Lord Caitanya, one who chants the maha-mantra (Hare Krsna, Hare Krsna, Krsna Krsna, Hare Hare/ Hare Rama, Hare Rama, Rama Rama, Hare Hare) attains the highest perfectional stage which had previously been attained by people who entered the ocean and executed austerities for ten thousand years. In this age of Kali, if a person does not take advantage of chanting the Hare Krsna mantra, which is offered as a great concession to the fallen human beings of this age, it is to be understood that he will become very much bewildered by the illusory energy of the Lord.    (More...)
