Real yoga is buddhi-yoga, the yoga of devotional service, which brings about direct perception of the Supreme Lord. When the devotee meets the Lord face to face, liberation takes the form of a woman and is at his beck and call, eager to serve him, and she is accompanied by personified material opulence, sense pleasure, and religiosity, all of whom wait upon the devotee like servants. The pure devotees of the Lord are all embodiments of perfection in yoga; thus the four Vedic goals are truly at their beck and call. And beyond these four goals is the supreme destination: superconsciousness, or God consciousness. This is the fifth and paramount Vedic goal. One who has reached the state of unalloyed Kṛṣṇa consciousness is an extremely rare personality—one in a million devotees, according Lord Caitanya.
(Renunciation through Wisdom).

When a person fixes his mind on the eternal, exquisite form of Śyāmasundara, the blackish, beautiful Lord Kṛṣṇa, all distress and anguish are vanquished. In the initial stages, the attempt to fix the mind on Kṛṣṇa may be unsuccessful, but with regulated practice (abhyāsa-yoga) it becomes possible. Abhyāsa-yoga means sincere engagement in the ninefold process of bhakti, beginning with hearing and chanting the holy name, pastimes, and so on, of Lord Kṛṣṇa. Proper execution of abhyāsa-yoga culminates in the awakening of divine consciousness, or superconsciousness. This is true success.
(Renunciation through Wisdom).

Considering everything material, some people make a show of renunciation and reject even those things that can be used in the Lord's service. This is futile. All objects in the material world are meant not for our enjoyment or gratification but for the Lord's service. This is the mood of one in transcendental consciousness, or superconsciousness. And all activities performed in this consciousness constitute true renunciation, or yukta-vairāgya, as opposed to false renuniciation, or phalgu-vairāgya. By instructing Arjuna to act in this way, the Supreme Lord has ordered us to do so as well. It is our duty to execute His instruction. Whatever the result may be, we must be convinced that all such activities are all-auspicious.
(Renunciation through Wisdom).

The living entity becomes bound up by the ropes of ignorance, duality, and illusion as soon as he sees this material world through the coloured crystal known as "me and mine." To nullify such false ego and contaminated consciousness, one must follow the process of buddhi-yoga, which is uncontaminated by the three modes of nature (ignorance, passion, and goodness). Otherwise superconsciousness is unattainable.
(Renunciation through Wisdom).

As spirit is not annihilated even after the annihilation of the material body, so also spiritual consciousness is not annihilated. Śrī Nārada developed this spiritual consciousness even when he had his material body in the previous kalpa. Consciousness of the material body means spiritual consciousness expressed through the medium of a material body. This consciousness is inferior, destructible and perverted. But superconsciousness of the supramind in the spiritual plane is as good as the spirit soul and is never annihilated.
(Srimad Bhagavatam-----1:6:4-----purport).

Uddhava is one of the eternal associates of the Lord, and a plenary portion of Uddhava was one of the eight Vasus in the days of yore. The eight Vasus and the demigods in the upper planetary system, who are responsible for the management of the universal affairs, performed a sacrifice in the days of yore, desiring to fulfill their respective ultimate goals in life. At that time an expansion of Uddhava, acting as one of the Vasus, desired to become an associate of the Lord. The Lord knew this because He is present in the heart of every living entity as Paramātmā, the Superconsciousness. In everyone's heart there is the representation of the Superconsciousness, who gives memory to the partial consciousness of every living entity. The living entity, as partial consciousness, forgets incidents of his past life, but the Superconsciousness reminds him how to act in terms of his past cultivation of knowledge. Bhagavad-gītā confirms this fact in various ways: ye yathā māṁ prapadyante tāṁs tathaiva bhajāmy aham (B.G.4:11), sarvasya cāhaṁ hṛdi sanniviṣṭo mattaḥ smṛtir jñānam apohanaṁ ca (B.G.15:15).
(Srimad Bhagavatam-----3:4:11-----purport).

The bhakti process, as performed under the regulative principles of vaidhī-bhakti, or devotional service following the prescribed rules and regulations, is defined by the revealed scriptures and confirmed by great ācāryas. This practice can help the neophyte devotee to rise to the stage of rāga-bhakti, in which the Lord responds from within as the caitya-guru, or the spiritual master as Superconsciousness. All transcendentalists other than devotees make no distinction between the individual soul and the Supersoul because they miscalculate the Superconsciousness and the individual consciousness to be one and the same. Such miscalculation by the nondevotees makes them unfit to receive any direction from within, and therefore they are bereft of the direct cooperation of the Lord.
(Srimad Bhagavatam-----3:5:4-----purport).

It is stated in Bhagavad-gītā that a person who is always absorbed in Kṛṣṇa consciousness is the topmost yogī. What is Kṛṣṇa consciousness? As the individual soul is present by his consciousness throughout his entire body, so the Supersoul, or Paramātmā, is present throughout the whole creation by superconsciousness. This superconscious energy is imitated by the individual soul, who has limited consciousness. I can understand what is going on within my limited body, but I cannot feel what is going on in another's body. I am present throughout my body by my consciousness, but my consciousness is not present in another's body. The Supersoul, or Paramātmā, however, being present everywhere and within everyone, is also conscious of everyone's existence.
(Srimad Bhagavatam-----3:5:45-----purport).

The theory that the soul and the Supersoul are one is not acceptable because it is not confirmed by authoritative Vedic literature. The individual soul's consciousness cannot act in superconsciousness. This superconsciousness can be achieved, however, by dovetailing individual consciousness with the consciousness of the Supreme. This dovetailing process is called surrender, or Kṛṣṇa consciousness. From the teachings of Bhagavad-gītā we learn very clearly that Arjuna, in the beginning, did not want to fight with his brothers and relatives, but after understanding Bhagavad-gītā he dovetailed his consciousness with the superconsciousness of Kṛṣṇa. He was then in Kṛṣṇa consciousness.
(Srimad Bhagavatam-----3:5:45-----purport).

The Lord is described as the soul, or spirit. What is the definition of spirit? Spirit is perceivable everywhere. Brahman means "great." His greatness is perceived everywhere. And what is that greatness? Consciousness. We have personal experience of consciousness, for it is spread all over the body; in every hair follicle of our body we can feel consciousness. This is individual consciousness. Similarly, there is superconsciousness. The example can be given of a small light and the sunlight. The sunlight is perceived everywhere, even within the room or in the sky, but the small light is experienced within a specific limit. Similarly, our consciousness is perceived within the limit of our particular body, but the superconsciousness, or the existence of God, is perceived everywhere. He is present everywhere by His energy.
(Srimad Bhagavatam-----3:26:3-----purport).

Svāyambhuva Manu instructs that whatever exists, not only in the spiritual world but even within this material world, is the property of the Supreme Personality of Godhead, who is present everywhere as the Superconsciousness. As confirmed in Bhagavad-gītā (13.3), kṣetra-jñam cāpi māṁ viddhi sarva-kṣetreṣu bhārata: in every field—in other words, in every body—the Supreme Lord is existing as the Supersoul. The individual soul is given a body in which to live and act according to the instructions of the Supreme Person, and therefore the Supreme Person also exists within every body. We should not think that we are independent; rather, we should understand that we are allotted a certain portion of the total property of the Supreme Personality of Godhead.
(Srimad Bhagavatam-----8:1:10-----purport).

The material nature is there, but without the soul's presence, the consciousness being there, it will not work. Therefore as this universe, material cosmic manifestation is working very nicely, you have to accept there is God. You cannot deny. So that consciousness, superconsciousness, that is different. You cannot say that "I am the same. I have got superconsciousness." That is not possible. Then, if you have got superconsciousness, why don't you feel about my pains and pleasure? The superconsciousness is of Viṣṇu. That is all-pervading consciousness. That is also the same. Nature is the same. As I have got my consciousness all over this body, similarly, the superconsciousness is there all over the universe. As I feel pains and pleasure on account of some disturbance on this body, similarly, as soon as we create some disturbance with this universal atmosphere, the supreme consciousness is disturbed. That disturbance is going on. Therefore, in spite of all arrangement... Pūrṇam idaṁ pūrṇam adaḥ pūrṇāt pūrṇam udacyate (Īśopaniṣad, Invocation). That, by God's creation, everything is complete. There is no flaw. But because we are creating disturbances, the world situation is different.
(Lecture on Bhagavad-gita-----2:17).

Consciousness is described in the Bhagavad-gītā: yena sarvam idaṁ tatam. The consciousness is distributed throughout your whole body. That we can make an experiment. But this consciousness is not, I mean to..., spread over all the cosmic manifestation. That is also a fact. My consciousness is spread over my body. Your consciousness is spread over your body. I do not know what you are thinking now, and you do not know what I am thinking. Therefore my consciousness, individual; your consciousness, individual. But there is the Supersoul who knows what you are thinking and what I am thinking, what he is thinking, everyone thinking. That is superconsciousness.
(Lecture on Bhagavad-gita-----2:51-55).
