Å›rÄ«-bÄdarÄyaṇiḥ uvÄca - ÅšrÄ« Åšukadeva GosvÄmÄ« said; evam - thus; vyavasitaḥ - fixed; buddhyÄ - by intelligence; samÄdhÄya - for concentration; manaḥ - the mind; há¹›di - in consciousness or in the heart; jajÄpa - he chanted; paramam - a supreme; jÄpyam - mantra he had learned from great devotees; prÄk-janmani - in his previous birth; anuÅ›iká¹£itam - practiced.
Such remembrance is described in Bhagavad-gÄ«tÄ (6.43-44):
tatra taá¹ buddhi-saá¹yogaá¹
labhate paurva-dehikam
yatate ca tato bhūyaḥ
saá¹siddhau kuru-nandana
pÅ«rvÄbhyÄsena tenaiva
hriyate hy avaśo ’pi saḥ
In these verses it is assured that even if a person engaged in devotional service falls down, he is not degraded, but is placed in a position in which he will in due course of time remember the Supreme Personality of Godhead. As explained later, Gajendra was formerly King Indradyumna, and somehow or other in his next life he became King of the elephants. Now Gajendra was in danger, and although he was in a body other than that of a human being, he remembered the stotra he had chanted in his previous life. Yatate ca tato bhÅ«yaḥ saá¹siddhau kuru-nandana. To enable one to achieve perfection, Kṛṣṇa gives one the chance to remember Him again. This is proved here, for although the King of the elephants, Gajendra, was put in danger, this was a chance for him to remember his previous devotional activities so that he could immediately be rescued by the Supreme Personality of Godhead.
It is imperative, therefore, that all devotees in Kṛṣṇa consciousness practice chanting some mantra. Certainly one should chant the Hare Kṛṣṇa mantra, which is the mahÄ-mantra, or great mantra, and also one should practice chanting cintÄmaṇi-prakara-sadmasu or the Ná¹›siá¹ha strotra (ito ná¹›siá¹haḥ parato ná¹›siá¹ho yato yato yÄmi tato ná¹›siá¹haḥ). Every devotee should practice in order to chant some mantra perfectly so that even though he may be imperfect in spiritual consciousness in this life, in his next life he will not forget Kṛṣṇa consciousness, even if he becomes an animal. Of course, a devotee should try to perfect his Kṛṣṇa consciousness in this life, for simply by understanding Kṛṣṇa and His instructions, after giving up this body one can return home, back to Godhead. Even if there is some falldown, practice of Kṛṣṇa consciousness never goes in vain. For example, AjÄmila, in his boyhood, practiced chanting the name of NÄrÄyaṇa under the direction of his father, but later, in his youth, he fell down and became a drunkard, woman-hunter, rogue and thief. Nonetheless, because of chanting the name of NÄrÄyaṇa for the purpose of calling his son, whom he had named NÄrÄyaṇa, he became advanced, even though he was involved in sinful activities. Therefore, we should not forget the chanting of the Hare Kṛṣṇa mantra under any circumstances. It will help us in the greatest danger, as we find in the life of Gajendra.
