Lord Krishna is only ever understood in His fullness through the Gaudiya Vaisnava acaryas the param para that Sri Caitanya Mahāprabhu has also become part of . Unless one is properly situated at their lotus feet , ones expression and devotion will be tinged with degrees of Jnana,  karma, and degrees of offenses , which waylay the trancendental traveller. Lord Krishna is understood to different degrees , such as Brahman,  paramatma, and Bhagavan.  As Bhagavan He described in three ways …   “Kṛṣṇa is complete in the spiritual sky [Vaikuṇṭha], He is more complete in Mathurā and Dvārakā, and He is most complete in Vṛndāvana, Vraja . due to His manifesting all His opulences. Spiritually and philosophically, Krishna is manifested in everything and is  everything , yet he is not manifest. This He explains in the Bhagavad Gita , His supreme mysterious workings and trancendental existence. Sri Caitanya Mahāprabhu has nicely defined everything in His statement that the living beings are simultaneously one and different from Divinity.  The Brahman energies manifested throughout the spiritual and material planes can be thought of in the same ways . The upshot is Krishna is fully present to those whom He chooses to be present to .

The cit sakti,  which brings trancendental jnana and Bhakti, is present through this method .

śṛṇvatāṁ sva-kathāḥ kṛṣṇaḥ
puṇya-śravaṇa-kīrtanaḥ
hṛdy antaḥ stho hy abhadrāṇi
vidhunoti suhṛt satām

Śrī Kṛṣṇa, the Personality of Godhead, who is the Paramātmā [Supersoul] in everyone’s heart and the benefactor of the truthful devotee, cleanses desire for material enjoyment from the heart of the devotee who has developed the urge to hear His messages, which are in themselves virtuous when properly heard and chanted

And in His lila sakti He is present explained here .

nāma cintāmaṇiḥ kṛṣṇaś
caitanya-rasa-vigrahaḥ
pūrṇaḥ śuddho nitya-mukto
’bhinnatvān nāma-nāminoḥ

Translation

“ ‘The holy name of Kṛṣṇa is transcendentally blissful. It bestows all spiritual benedictions, for it is Kṛṣṇa Himself, the reservoir of all pleasure. Kṛṣṇa’s name is complete, and it is the form of all transcendental mellows. It is not a material name under any condition, and it is no less powerful than Kṛṣṇa Himself. Since Kṛṣṇa’s name is not contaminated by the material qualities, there is no question of its being involved with māyā. Kṛṣṇa’s name is always liberated and spiritual; it is never conditioned by the laws of material nature. This is because the name of Kṛṣṇa and Kṛṣṇa Himself are identical.’

Although Krishna comes to this world personally or through His expansions and incarnations for many purposes , most importantly , his glorious activities are to be remembered and meditated upon , and heard about through the param para devotees who relish them in full . The six Goswami’s of Vrndavana have further elaborated upon the Srimad Bhagavatam and their confidential writings are windows to the spiritual kingdoms,  they are all eternal residents of those kingdoms and appear within the Vraj lila and Mahaprabhu’s lila . Krishna’s all attractive pastimes are eternally manifest, and one who surrenders the heart and mind with an attitude of service and devotion and following strictly in the footsteps of the param para acaryas immediately contacts the eternal spiritual plane by their grace .
