"Actually, every living entity is intended to abide by the dictation of the Supreme Personality of Godhead, who is seated in everyone's heart as Paramātmā. When the mind is misled by the external illusory energy, one becomes entangled in material activities. Therefore, as soon as one's mind is controlled through one of the yoga systems, one is to be considered as having already reached the destination. One has to abide by superior dictation. When one's mind is fixed on the superior nature, he has no other alternative but to follow the dictation of the Supreme. The mind must admit some superior dictation and follow it. The effect of controlling the mind is that one automatically follows the dictation of the Paramātmā or Supersoul. Because this transcendental position is at once achieved by one who is in Kṛṣṇa consciousness, the devotee of the Lord is unaffected by the dualities of material existence, namely distress and happiness, cold and heat, etc. This state is practical samādhi, or absorption in the Supreme."
(Bhagavad-gītā As It Is 6.7, Purport)
"There are many other theories, but all these different speculations are at once cleared off as soon as Śrī Kṛṣṇa is realized in truth by the process of bhakti-yoga. Śrī Kṛṣṇa is like the sun, and the materialistic speculations about the Absolute Truth are like the darkest midnight. As soon as the Kṛṣṇa sun is arisen within one's heart, the darkness of materialistic speculations about the Absolute Truth and the living beings is at once cleared off. In the presence of the sun, the darkness cannot stand, and the relative truths that were hidden within the dense darkness of ignorance become clearly manifested by the mercy of Kṛṣṇa, who is residing in everyone's heart as the Supersoul."
(Śrīmad-Bhāgavatam 1.2.21, Purport)
"The Supersoul, being seated in everyone's heart, can witness everyone's activities—past, present and future. In the Upaniṣads the Supersoul is described as being seated with the individual soul as friend and witness. As a friend, the Lord is always anxious to get back His friend, the individual soul, and bring him back home, back to Godhead. As a witness He is the bestower of all benedictions, and He endows each individual with the result of his actions. The Supersoul gives the individual soul all facilities to achieve whatever he desires to enjoy in this material world. Suffering is a reaction to the living entity's propensity to try to lord it over the material world. But the Lord instructs His friend, the individual soul, who is also His son, to give up all other engagements and simply surrender unto Him for perpetual bliss and an eternal life full of knowledge."
(Śrīmad-Bhāgavatam 3.15.45, Purport)
"A devotee is inspired by the Supersoul within the heart to advance in devotional service in a variety of ways. The devotee does not feel hackneyed or stereotyped, nor does he feel that he is in a stagnant position. In the material world, if one engages in chanting a material name, he will feel tired after chanting a few times. However, one can chant the Hare Kṛṣṇa mahā-mantra all day and night and never feel tired. As chanting is increased, it will come out new and fresh. Śrīla Rūpa Gosvāmī said that if he could somehow get millions of ears and tongues, then he could relish spiritual bliss by chanting the Hare Kṛṣṇa mahā-mantra. There is really nothing uninspiring for a highly advanced devotee. In Bhagavad-gītā the Lord says that He is situated in everyone's heart and that He helps the living entity forget and remember. By the grace of the Lord, the devotee gets inspiration."
(Śrīmad-Bhāgavatam 4.30.20, Purport)
"The Supreme Personality of Godhead, the Supersoul within the core of everyone's heart, gives inspirations for action according to one's mentality. All of these mentalities are merely facilities given by Kṛṣṇa to the person acting. Bhagavad-gītā therefore says, mattaḥ smṛtir jñānam apohanaṁ ca: (BG 15.15) everyone works according to the inspiration given by the Supersoul. Because everyone has a different goal of life, everyone acts differently, as guided by the Supreme Personality of Godhead."
(Śrīmad-Bhāgavatam 7.9.20, Purport)
"Regarding the Christian's Trinity, I believe it is called God, the Holy Ghost, and the son. Person in Krishna Consciousness accepts this by the name Visnu, Paramatma, and Jiva. God is a Person, the holy spirit or the supersoul is a person, and the living entity is also a person. Also, Mary is the representation of the energy of God. Either as internal energy Radharani or as external energy Durga, the energy of Godhead can be considered the mother of the living entities. But there is no clash between the Bible and the Vedas, simply some people formulate their personal ideas and cause quarrelings. Nobody can say the Bible was meant for the same class of men as the Bhagavad Gita. And Bhagavad Gita is the ABC's of spiritual knowledge. Beyond that is Srimad Bhagwatam. How great Srimad Bhagwatam is nobody can imagine. And beyond that is Chaitanya Charitamrita. But beginning from the Bible or Koran, on up the principle remains the same. Just like beginning from the pocket dictionary, up."
(Srila Prabhupada Letter, April 19, 1968)
"Don't feel yourself to be alone because Krishna is always with you. Krishna is always with every living entity as Supersoul, and to His devotee especially He talks and gives instructions how to attain the perfectional stage of meeting Him. So don't feel alone. Always chant whenever possible, read our books, and there will be no great difficulty."
(Srila Prabhupada Letter, April 3, 1969)
"Regarding the statement in Bhagavad Gita (17.6) that those who are demons parch the Supersoul within the body, Krishna cannot be parched, but one who observes fasting irregularly gives unnecessary trouble to the soul; and the soul and the Supersoul sitting together or the soul being part and parcel of the Supersoul, indirectly it is parching the Supersoul. The idea is that one should not unnecessarily give trouble to the soul or Supersoul. That is the business of the demon."
(Srila Prabhupada Letter, March 15, 1970)
"Regarding your question, this surrender to Supersoul is in the advanced stage of Krishna Consciousness. So long one is not advanced, he has to take information and direction from the representative of Supersoul or the Spiritual Master. The spiritual master is external manifestation of the Supersoul. Thus the Lord helps the living entity, helps both from inside & outside."
(Srila Prabhupada Letter, February 22, 1972)
"With regard to the offenses you are hearing it is not ghosts as you say, but they are creations of your mind. The mind is indeed wretched as you say. Therefore Krishna says that for the endeavoring transcendentalist he must first control the mind, and then by controlling the mind he will have peace. He says: jitamanah prasantasya, Paramatma smahitah. 'For one who has conquered the mind, the Supersoul is already reached, for he has attained tranquillity.' (BG 6.7) In this age the easiest method for controlling the mind, as taught to us by Lord Caitanya Mahaprabhu, is the chanting of Hare Krishna.
Do not give very much importance to this thing. Chant Hare Krishna. That is my instruction to you."
