Srila Prabhupada  quotes on rising during brahma muhurta
 
Chanting japa should be done early in the morning with full concentration preferably during the BrahmMuhurta time. Concentrate fully on the sound vibration of the mantra, pronouncing each name distinctly and gradually your speed in chanting will increase naturally. Do not worry so much about chanting fast, most important is the hearing. A devotee should always be grave and silent which means that he only discusses topics relating to Krishna Consciousness. Yes, spend your time chanting and reading and taking Krishna Prasadam and automatically your tongue will come under control. If you sincerely engage 24 hours daily in devotional service according to the instructions of the Spiritual Master, chant daily 16 rounds, attend the arati ceremony of Lord Krishna, associate with the devotees and adhere strictly to the regulative principles then Krishna will reveal Himself personally to you.

The time early in the morning, one and a half hours before sunrise, is called brāhma-muhūrta. During this brāhma-muhūrta, spiritual activities are recommended. Spiritual activities performed early in the morning have a greater effect than in any other part of the day.  SB 3.20.46
 
 
In the early morning hours (known as brāhma-muhūrta) one should get up and immediately chant the Hare Kṛṣṇmantra, or, at least, “Kṛṣṇa, Kṛṣṇa, Kṛṣṇa.” In this way, one should remember Kṛṣṇa. Some ślokas or prayers should also be chanted. By chanting, one immediately becomes auspicious and transcendental to the infection of material qualities. Actually one has to chant and remember Lord Kṛṣṇa twenty-four hours daily, or as much as possible   Madhya 24.331 
 
The brāhma-muhūrta takes place about one and a half hours before sunrise. It is recommended that one should rise from bed at that time and, after finishing daily ablutions, take to spiritual activities by performing Magala-ārātrika and chanting the Hare Kṛṣṇamantra. This period is very convenient for the execution of spiritual activities.  KB 1-32 / Description of the Rasa Dance
 
Lord Kṛṣṇa used to lie down with His sixteen thousand wives, but also He would rise up from bed very early in the morning, three hours before sunrise. By nature’s arrangement the crowing of the cocks warns of the brāhma-muhūrta hourThere is no need of alarm clocks; as soon as the cocks crow early in the morning, it is to be understood that it is time to rise from bed. Hearing that sound, Kṛṣṇa would get up from bed, but His rising early was not very much to the liking of His wives. The wives of Kṛṣṇa were so much attached to Him that they would lie in bed embracing Him, but as soon as the cocks crowed, Kṛṣṇa’s wives would be very sorry and would immediately condemn the crowing.
 KB 2-15 / Lord Krsna’s Daily Activities :
Although Śrīmatī Rukmiīdevī, the first queen of Lord Kṛṣṇa, knew that brāhma-muhūrta is the most auspicious time in the entire day, she would feel disgusted at the appearance of brāhma-muhūrta because she was not very happy to have Kṛṣṇa leave her side in bed. Despite Śrīmatī Rukmiīdevī’s disgust, Lord Kṛṣṇa would immediately get up from bed exactly on the appearance of brāhma-muhūrta. An ideal householder should learn from the behavior of Lord Kṛṣṇa how to rise early in the morning, however comfortably he may be lying in bed embraced by his wife,
KB 2-15 / Lord Krsna’s Daily Activities
 
After rising from bed, Lord Kṛṣṇa would wash His mouth, hands and feet and would immediately sit down and meditate on Himself. This does not mean, however, that we should also sit down and meditate on ourselves. We have to meditate upon Kṛṣṇa, Rādhā-Kṛṣṇa. That is real meditation, Kṛṣṇa is Krṣṇa Himself; therefore He was teaching us that   brāhma-muhūrta should be utilized for meditation on Rādhā-Kṛṣṇa. By doing so, Kṛṣṇa would feel very much satisfied, and similarly we will also feel transcendentally pleased and satisfied if we utilize the brāhma-muhūrta period to meditate on Rādhā and Kṛṣṇand if we think of how Śrī Rukmiīdevī and Kṛṣṇa acted as ideal householders to teach the whole human society to rise early in the morning and immediately engage in Kṛṣṇa consciousness. There is no difference between meditating on the eternal forms of Rādhā-Kṛṣṇa and chanting the     mahāmantra,     Hare Kṛṣṇa. As for Kṛṣna’s meditation, He had no alternative but to meditate on Himself. The object of meditation is Brahman, Paramātmā or the Supreme Personality of Godhead, but Kṛṣṇa Himself is all three: He is the Supreme Personality of Godhead, Bhagavān; the localized Paramātmā is His plenary partial expansion; and the all-pervading Brahman effulgence is the personal rays of His transcendental body.  KB 2-15 / Lord Krsna’s Daily Activities
 
So the other devotees, (laughs) they cannot rise…, come at five o’clock. That is the test. Yes. One who cannot rise early in the morning, he is not spiritually serious. That is test.Brāhma-muhūrta, this hour, one hour before sunrise, is very auspicious moment. Conversation – December 13, 1970, Indore
