Talks Between the Lord and Rāmānanda Rāva

“Out of many thousands among men, one may endeavor for perfection, and of those who have achieved perfection, hardly one knows Me in truth.” (Bg. 7.3)
The word  siddhaye  indicates liberation. Only after being liberated from material conditioning can one understand Kṛṣṇa. When one can understand Kṛṣṇa as He is ( tattvataḥ ), one actually lives in the spiritual world, although apparently living within the material body. This technical science can be understood when one is actually spiritually advanced.
In his  Bhakti-rasāmrta-sindhy  (1.2.18.7), Śrīla Rūpa Gosvāmī savs:
ihā yasya harer dāsye karmaṇā manasā girā nikhilāsv apy avasthāsu jīvan-muktaḥ sa ucyate
When a person in this material world desires only to serve Kṛṣṇa with love and devotion, he is liberated, even though functioning within this material world. As  Bhagavad-gītā  confirms:
māṁ ca yo ‘vyabhicāreṇa bhakti-yogena sevate sa gunān samatītyaitān brahma-bhūyāya kalpate
“One who engages in full devotional service, who does not fall down in any circumstance, at once transcends the modes of material nature and thus comes to the level of Brahman.” (Bg. 14.26)
Simply by engaging in the loving service of the Lord one can attain liberation. As stated in  Bhagavad-gītā  (18.54):  brahma-bhūtaḥ prasannātmā na śocati na kāṅkṣati . A person who is highly advanced in spiritual knowledge and who has attained the  brahma-bhūta  stage neither laments nor hankers for anything material. That is the stage of spiritual realization.
Śrīla Bhaktivinoda Ṭhākura considered the  brahma-bhūta  stage in two divisions— svarūpa-gata  and  vastu-gata . When one has understood Kṛṣṇa in truth but is still maintaining some material connection, he is known to be situated in his  svarūpa , his original consciousness. When that original consciousness is completely spiritual, it is called Kṛṣṇa consciousness. One who lives in such consciousness is actually living in Vṛndāvana. He may live anywhere; material location doesn't matter. When by the grace of Kṛṣṇa one thus advances, he becomes completely uncontaminated by the material body and mind and at that time factually lives in Vṛndāvana. That stage is called  vastu-gata .
One should execute his spiritual activities in the  svarūpa-gata  stage of consciousness. He should also chant the  cinmayī gāyatrī , the spiritual  mantras: oṁ
