An unalloyed devotee who has developed ecstatic love for Kṛṣṇa is always engaging his words in reciting prayers to the Lord. Within the mind he is always thinking of Kṛṣṇa, and with his body he either offers obeisances by bowing down before the Deity or engages in some other service.
(Nectar of Devotion).

Rūpa Gosvāmī next describes the characteristics of a person who has actually developed his ecstatic love for Kṛṣṇa. The characteristics are as follows:

(1) He is always anxious to utilize his time in the devotional service of the Lord. He does not like to be idle. He wants service always, twenty-four hours a day, without deviation.
(2) He is always reserved and perseverant.
(3) He is always detached from all material attraction.
(4) He does not long for any material respect in return for his activities.
(5) He is always certain that Kṛṣṇa will bestow His mercy upon him.
(6) He is always very eager to serve the Lord faithfully.
(7) He is very much attached to the chanting of the holy names of the Lord.
(8) He is always eager to describe the transcendental qualities of the Lord.
(9) He is very pleased to live in a place where the Lord's pastimes are performed, e.g., Mathurā, Vṛndāvana or Dvārakā.
(Nectar of Devotion).

When a devotee, in spite of possessing all the qualities of pure realization, is not proud of his position, he is called prideless. In the Padma Purāṇa it is stated that King Bhagīratha was the emperor above all other kings, yet he developed such ecstatic love for Kṛṣṇa that he became a mendicant and went out begging even to the homes of his political enemies and untouchables. He was so humble that he respectfully bowed down before them.
(Nectar of Devotion).

There are many statements about the festive days in connection with Kṛṣṇa's different activities. One of these festive days is Janmāṣṭamī, the day of Kṛṣṇa's birth. This Janmāṣṭamī day is the most opulent festival day for the devotees, and it is still observed with great pomp in every Hindu house in India. Sometimes even the devotees of other religious groups take advantage of this auspicious day and enjoy the performance of the ceremony of Janmāṣṭamī. Ecstatic love for Kṛṣṇa is also aroused on the days of Ekādaśī, which are other festive days in connection with Kṛṣṇa.
(Nectar of Devotion).

The bodily symptoms manifested by a devotee in expressing ecstatic love for Kṛṣṇa are called anubhāva. Practical examples of anubhāva are as follows: dancing, rolling on the ground, singing very loudly, stretching the body, crying loudly, yawning, breathing very heavily, neglecting the presence of others, drooling, laughing like a madman, wheeling the head and belching.
(Nectar of Devotion).

Bilvamaṅgala Ṭhākura said, "My dear Kṛṣṇa, You are leaving me, forcibly getting out of my clutches. But I shall be impressed by Your strength only when You can go forcibly from the core of my heart." This is an instance of feeling pride in ecstatic love for Kṛṣṇa.
(Nectar of Devotion).

When Brahmā was deluded by Kṛṣṇa, who expanded Himself into so many cowherd boys, calves and cows, Kṛṣṇa's elder brother, Śrī Baladeva (a direct expansion of Kṛṣṇa Himself), felt astonishment and said, "How wonderful it is that My ecstatic love for Kṛṣṇa is again being attracted to so many cowherd boys, calves and cows!"
(Nectar of Devotion).

This example of Mahārāja Parīkṣit's behavior, his remaining patient even at the last point of his life, his undisturbed condition of mind, is an example of reservation. This is one of the characteristics of a devotee who has developed ecstatic love for Kṛṣṇa.
(Nectar of Devotion).

Ecstatic love for Kṛṣṇa, which is known as anubhāva, is symptomized by the following signs: one becomes engaged exclusively in the service of the Lord, being attentive to carry out the orders of the Lord faithfully; one becomes undisturbed and nonenvious in full transcendental loving service to the Lord; and one makes friendship with the devotees of the Lord who are situated in faithful service to Him. All of these symptoms are called anubhāva, ecstatic love.
(Nectar of Devotion).

When one is actually advanced in ecstatic love for Kṛṣṇa, eight transcendental, blissful symptoms are manifest in the body. Those are the symptoms of perfection arising from loving service to the Supreme Personality, of Godhead. Since Mahārāja Bharata was constantly, engaged in devotional service, all the symptoms of ecstatic love were manifest in his body.
(Srimad Bhagavatam------5:7:12------purport).

Due to his deep ecstatic love for Kṛṣṇa, the mahā-bhāgavata sees Kṛṣṇa everywhere and nothing else. This is confirmed in the Brahma-saṁhitā (5.38): premāñjana-cchurita-bhakti-vilocanena santaḥ sadaiva hṛdayeṣu vilokayanti.
(Sri Caitanya Caritamrta------2:8:274------purport).

"I worship the primeval Lord, Govinda, who is always seen by the devotee whose eyes are anointed with the pulp of love. He is seen in His eternal form of Śyāmasundara, situated within the heart of the devotee." Those who are filled with ecstatic love for Kṛṣṇa always see the form of Śyāmasundara within their hearts.
(Sri Caitanya Caritamrta------2:19:102------purport).

Devotional service is always dormant in everyone'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.
(Sri Caitanya Caritamrta------2:19:177------purport).

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.”
(Sri Caitanya Caritamrta------2:19:177------purport).
