As spirit souls we are part and parcel of the Supreme Spirit, but due to our desire to enjoy this material world, we have been put into material nature. Yet in whatever species of life we may be, Kṛṣṇa is the Father. Thus Bhagavad-gītā is not meant for any particular party or nation but for everyone all over the world… In this way people may realize their true spiritual nature and their relationship to the supreme spiritual whole.
“And when you have thus learned the truth, you will know that all living beings are but parts of Me—and that they are in Me, and are Mine. Even if you are considered to be the most sinful of all sinners, when you are situated in the boat of transcendental knowledge, you will be able to cross over the ocean of miseries. As a blazing fire burns firewood to ashes, O Arjuna, so does the fire of knowledge burn to ashes all the reactions to material activities.” (Bg. 4.35–37)

Knowledge as Faith in Guru and surrender to Kṛṣṇa
In the Fourth Chapter of Bhagavad-gītā Śrī Kṛṣṇa concludes that of all sacrifices, the best is the acquisition of knowledge.

“O chastiser of the enemy, the sacrifice of knowledge is greater than the sacrifice of material possessions. O son of Pṛthā, after all, the sacrifice of work culminates in transcendental knowledge.” (Bg. 4.33)
Knowledge is the best sacrifice because this conditional life is due to ignorance. The purpose of sacrifice, penance, yoga and philosophical discussion is to acquire knowledge. There are three stages of transcendental knowledge by which one realizes the impersonal aspect of God (Brahman realization), the localized aspect of God within the heart and within every atom (Paramātmā or Supersoul realization) and the realization of the Supreme Personality of Godhead (Bhagavān realization). But the very first step in acquiring knowledge is coming to understand that “I am not this body. I am spirit soul, and my aim of life is to get out of this material entanglement.” The point is that whatever sacrifice we make is intended to enable us to come to the point of real knowledge. The highest perfection of knowledge is given in Bhagavad-gītā as surrender to Kṛṣṇa (bahūnāṁ janmanām ante jñānavān māṁ prapadyate) (Bg. 7.19). The jñānavān, not the fool, surrenders unto Kṛṣṇa, and that is the highest stage of knowledge. Similarly, at the end of Bhagavad-gītā Śrī Kṛṣṇa advises Arjuna:
