Who cannot know God?


Na cāsya kaścin nipuṇena dhātur
Avaiti jantuḥ kumanīṣa ūtīḥ।
Nāmāni rūpāṇi manovacobhiḥ
Santanvato naṭa-caryām ivājñaḥ॥- Shrimad Bhagwat Mahapuran (1.3.37)
Just as an ignorant person is unable to understand the miracles performed by a magician or an actor through his thoughts and words, similarly, a person with bad intellect is unable to recognize the various names and forms of God and his divine acts, revealed by his true thoughts and the words of the Vedas, through many logical arguments.
Tvayāhaṃ toṣitaḥ samyag vedagarbha sisṛkṣayā।
Ciraṃ bhṛtena tapasā dustoṣaḥ kūṭa-yoginām॥- Shrimad Bhagwat Mahapuran (2.9.19)
Shri Bhagwan said- Brahmaji! The knowledge of all the Vedas is present in your heart. You have satisfied me well by performing penance for a long time with the desire to create the universe. Those who practice yoga with deceit in their minds can never please me.
Ātmātmajāpta-gṛha-vitta-janeṣu saktaiḥ
Duṣprāpaṇāya guṇa-saṅga-vivarjitāya।
Muktātmabhiḥ sva-hṛdaye paribhāvitāya
Jñānātmane bhagavate nama īśvarāya॥Shrimad Bhagwat Mahapuran (8.3.18)
Those who are attached to their body, children, teachers, home, property, and relatives, it is very difficult for them to attain you. Because you are free from attachment to qualities. The liberated souls constantly think of you in their hearts. I bow to that God who is full of all the divine knowledge.
