The gradual process of development to the stage of devotional service is explained in the Śrīmad-Bhāgavatam, First Canto: "The beginning is to hear about Lord Kṛṣṇa in the association of devotees who have themselves cleansed their hearts by association. Hearing about the transcendental activities of the Lord will result in one's feeling transcendental bliss always." It is also explained in the Bhagavad-gītā that for one who has actually come to the spiritual platform, the first symptom visible will be that he is always joyful. This joyous life is attained by one's reaction to reading the Bhagavad-gītā or Śrīmad-Bhāgavatam, or else from associating with persons who are very interested in the spiritual life of Kṛṣṇa consciousness-specifically those who have made the determination to achieve the favor of Govinda by being engaged in transcendental loving service at His lotus feet. Being encouraged by such a feeling, one who is constantly engaged in discharging the regulative principles of devotional service in such a way as to please the Supreme Personality of Godhead develops two principles of compelling force, which come under the heading of vibhāva. Thus one enjoys transcendental bliss.
