awaken one to devotional service. Devotional service is always dormant in every-one's heart, and by the offenseless chanting of the holy names of the Lord, one's original dormant Kṛṣṇa consciousness is awakened. This awakening to Kṛṣṇa consciousness is the beginning of  sādhana-bhakti . This can be divided into many different parts, including faith, association with devotees, initiation by the spiritual master, engagement in devotional service under the instructions of a spiritual master, steadiness in devotional service and the awakening of a taste for devotional service. In this way, one can become attached to Kṛṣṇa and His service, and when this attachment is intensified, it results in ecstatic love for Kṛṣṇa. The word  rati  is explained in the  Bhakti-rasāmṛta-sindhu  (1.3.41) as follows:
vyaktaṁ masṛṇatevāntar-lakṣyate rati-lakṣaṇam mumukṣu-prabhṛtīnāṁ ced bhaved eṣā ratir na hi
“When a tenderness of the heart is manifest, there is  rati , or attachment. Those who are interested in being liberated from material bondage must manifest this tenderness called  rati .” This attachment is not like material attachment. When one is liberated from material contamination, the awakening of attachment for Kṛṣṇa’s service is called  rati . In the material world there is attachment for material enjoyment, but this is not  rati . Transcendental  rati  can be awakened only on the spiritual platform. Ecstatic love for Kṛṣṇa ( prema ) is described in the  Bhakti-rasāmṛta-sindhu  (1.41) as follows:
samyaṅ masṛṇita-svānto mamatvātiśayāṅkitaḥ bhāvaḥ sa eva sāndrātmā budhaiḥ premā nigadyate
“When the heart is completely softened and devoid of all material desires and when one’s emotional feelings become very strong, one becomes very much attached to Kṛṣṇa. Such purified emotion is known as pure love.”
