"We should always try to mold the activities of our lives in such a way that we will constantly remember Viṣṇu, or Kṛṣṇa. That is Kṛṣṇa consciousness. Whether one concentrates his mind on the four-handed form of Viṣṇu or on the form of two-handed Kṛṣṇa, it is the same. The Padma Purāṇa recommends: somehow or other always think of Viṣṇu, without forgetting Him under any circumstances. Actually this is the most basic of all regulative principles. For, when there is an order from a superior about doing something, there is simultaneously a prohibition. When the order is that one should always remember Kṛṣṇa, the prohibition is that one should never forget Him. Within this simple order and prohibition, all regulative principles are found complete."
(Nectar of Devotion, Chapter 2)
"Just like Prahlada Maharaja always remembered Krishna and that saved Him from the most difficult situations. If we constantly remember to take shelter only at Krishna's Lotus Feet, then we shall always be saved from all sorts of dangers."
(Srila Prabhupada Letter, June 12, 1972)
"Although Prahlāda Mahārāja was only a boy, he had no interest in playing. As stated in Śrīmad-Bhāgavatam (11.2.42), viraktir anyatra ca: the symptom of perfect Kṛṣṇa consciousness is that one loses interest in all material activities. For a small boy to give up playing is impossible, but Prahlāda Mahārāja, being situated in first-class devotional service, was always absorbed in a trance of Kṛṣṇa consciousness. Just as a materialistic person is always absorbed in thoughts of material gain, a mahā-bhāgavata like Prahlāda Mahārāja is always absorbed in thoughts of Kṛṣṇa."
(Śrīmad-Bhāgavatam 7.4.37, Purport)
"Regarding your first question, is it offensive to think of Krishna's Pastimes while chanting, I think you should know that it is not offensive, but rather it is required. One must try for the point when he simply hears Krishna and immediately all of Krishna, His Pastimes, His Form, His Quality, are in his thoughts. So to always be immersed in thoughts of Krishna this is our process. When we are full in Krishna then where there can be any chance for maya in us? So this is our duty to remember Krishna's Pastimes. One who cannot remember Krishna, let him always hear Hare Krishna and then when he has perfected this art, then always he will remember Krishna, His Activities, His Qualities, etc."
(Srila Prabhupada Letter, December 4, 1968)
"We can remember Krishna in every moment. We can remember Krishna while taking a glass of water because the taste of water is Krishna. We can remember Krishna as soon as we see the sunlight in the morning, because the sunlight is a reflection of Krishna's Bodily Effulgence. Similarly, as soon as we see moonlight in the evening we remember Krishna because moonlight is also reflection of sunlight. Similarly, when we hear any sound we can remember Krishna because sound is Krishna, and the most perfect sound, transcendental, is Hare Krishna, which we have to chant 24 hours. So there is no scope of forgetting Krishna at any moment of our life provided we practice in that way."
(Srila Prabhupada Letter, January 11, 1968)
"So why don't you do this, four things, very easy things? Is it very difficult to constantly remember Kṛṣṇa? You can do it. You are remembering something. A mind is occupied always with something. Just practice to occupy the mind with Kṛṣṇa, that's all. Where is the difficulty? Man-manā bhava mad-bhakto mad-yājī māṁ namas... Everything is there. You practice it... Sa vai manaḥ kṛṣṇa-padāravindayor (SB 9.4.18). Mahārāja Ambarīṣa, he was a great emperor of this world, but his mind was fixed up on the lotus feet of Kṛṣṇa. Sa vai manaḥ kṛṣṇa-padaravindayor vacāṁsi vaikuṇṭha-guṇānuvarṇane. When you talk, you will talk about Kṛṣṇa only. You practice. You see, you see Kṛṣṇa's picture, Kṛṣṇa's Deity. You hear Kṛṣṇa's topics, Bhagavad-gītā, Śrīmad-Bhāgavatam. In, in this way engage all your senses: your seeing power, your hearing power, your talking power, your eating power, your sleeping power. Everything, if you make Kṛṣṇa conscious, then generally or automatically, you'll remember at the time of death Kṛṣṇa. And as soon as you remember Kṛṣṇa, ante nārāyaṇa-smṛtiḥ (SB 2.1.6), then your life is perfect. There is no difficulty. Simply you have to practice. Abhyāsa-yoga-yuktena cetasā nānya-gāminā (BG 8.8). Don't allow your mind to go astray, then everything is all right."
(Srila Prabhupada Lecture, Hyderabad, April 15, 1975)
"The bhakti-yogī always thinks of Kṛṣṇa, and therefore at the time of death he can very easily transfer himself to Kṛṣṇaloka, without even perceiving the pains of death."
(Śrīmad-Bhāgavatam 6.10.12, Purport)
"Either in waking or in sleep, a devotee of the Lord can never be free from thinking of Kṛṣṇa's name, form, qualities and pastimes. Thus a devotee of Kṛṣṇa can conquer both sleep and ignorance simply by thinking of Kṛṣṇa constantly. This is called Kṛṣṇa consciousness, or samādhi."
(Bhagavad-gītā As It Is 1.24, Purport)
"The pure devotee of the Lord enjoys life by constantly remembering the lotus feet of the Lord by hearing kṛṣṇa-kathā. For such a devotee there is no such thing as material existence, and the much advertised bliss of brahmānanda is like a fig for the devotee who is in the midst of the transcendental ocean of bliss."
(Śrīmad-Bhāgavatam 3.5.13, Purport)
"Do not waste any time, but work always to please Krishna within your heart. He is witnessing everything. He only wants us to constantly remember Him. Is it very difficult?"
(Srila Prabhupada Letter, August 21, 1975)
"Devotees who are always absorbed in thoughts of Kṛṣṇa will soon see Kṛṣṇa face to face without a doubt. In other words, devotees who are always engaged in Kṛṣṇa consciousness and are fully absorbed in thoughts of Kṛṣṇa certainly return home, back to Godhead. They then see Kṛṣṇa directly, face to face, talk with Him and enjoy His company. This is confirmed in the Bhagavad-gītā (4.9): tyaktvā dehaṁ punar janma naiti mām eti so ’rjuna.
Because during his lifetime a pure devotee is always speaking of Kṛṣṇa and engaging in His service, as soon as he gives up his body he immediately returns to Goloka Vṛndāvana, where Kṛṣṇa is personally present. He then meets Kṛṣṇa directly. This is successful human life."
(Caitanya-caritāmṛta Madhya 13.155, Purport)
