Bhagavad Gita 2.41:
Those who are on this path are resolute in purpose, and their aim is one. O beloved child of the Kurus, the intelligence of those who are irresolute is many-branched.
PURPORTA strong faith that by Krsna consciousness one will be elevated to the highest perfection of life is called vyavasāyātmikā intelligence. The CC Madhya 22.62 states:
sraddha sabde visvasa kahe su-drdha niscaya
krsna-bhakti kaile sarva karma krta haya'
Faith means unflinching trust in something sublime. When one is engaged in the duties of Krsna consciousness, he need not act in relationship to the material world with obligations to family traditions, humanity, or nationality. Fruitive activities are the engagements of one's reactions from past good or bad deeds. When one is awake in Krsna consciousness, he need no longer endeavor for good results in his activities. When one is situated in Krsna consciousness, all activities are on the absolute plane, for they are no longer subject to dualities like good and bad.
The resolute purpose of a person in Krsna consciousness is based on knowledge. A person in Krsna consciousness is the rare good soul who knows perfectly that Vāsudeva, or Kṛṣṇa, is the root of all manifested causes. As by watering the root of a tree one automatically distributes water to the leaves and branches, so by acting in Krsna consciousness one can render the highest service to everyone — namely self, family, society, country, humanity, etc. If Krsna is satisfied by one's actions, then everyone will be satisfied.
Service in Kṛṣṇa consciousness is, however, best practiced under the able guidance of a spiritual master who is a bona fide representative of Kṛṣṇa, who knows the nature of the student and who can guide him to act in Kṛṣṇa consciousness.
Śrīla Viśvanātha Cakravartī Ṭhākura instructs us, in his famous prayers for the spiritual master, as follows:
yasya prasādād bhagavat-prasādo
"By satisfaction of the spiritual master, the Supreme Personality of Godhead becomes satisfied. And by not satisfying the spiritual master, there is no chance of being promoted to the plane of Kṛṣṇa consciousness. I should, therefore, meditate and pray for his mercy three times a day, and offer my respectful obeisances unto him, my spiritual master."
The whole process, however, depends on perfect knowledge of the soul beyond the conception of the body — not theoretically but practically, when there is no longer a chance for sense gratification manifested in fruitive activities. One who is not firmly fixed in mind is diverted by various types of fruitive acts.
