“Discussing Kṛṣṇa in a humble and loving mood is the best thing to do, it is the main practice of devotion. It impels Kṛṣṇa to purify his dwelling place, your heart. As the heart becomes more pure, one engages even more attentively and fixedly in this practice of devotion.”
The above quote (Śrīmad Bhāgavat Purāṇa 1.2.17 & 18) describes the progress of divine love from the third to the fifth stage.
The third stage of divine love is Practice. Above all, the primary way to practice divine love is by “hearing and chanting” about the beloved, Kṛṣṇa. This quote says that discussing Kṛṣṇa in a devotional mood, full of humility and love, is the most auspicious way to practice divine love.
This auspicious practice – the third stage of devotion – stimulates the fourth stage of development: Purification. When we lovingly discuss Kṛṣṇa, his presence in our hearts resonates more and more loudly and brightly. Kṛṣṇa is the ultimate purity, so the amplification of his presence in our hearts stimulates our spontaneous internal purification.
As we become more pure, our practice of divine love comes more into the fifth stage of development. It becomes more deep, sincere, attentive and steady. In a word, it becomes more Fixed.
