"When one factually knows the opulence of the Supreme, there is no alternative but to surrender to Him... If, however, one thoroughly studies the different descriptions of the opulences and expansions of Krishna's energy, then one can understand without any doubt the position of Lord Shri Krishna and can fix his mind in the worship of Krishna without deviation.

How one can attain the highest devotional perfection of association with the Supreme Personality of Godhead has been thoroughly explained in this chapter. Śrīla Baladeva Vidyābhūṣaṇa, a great ācārya in disciplic succession from Kṛṣṇa, concludes his commentary on this chapter by saying,

yac-chakti-leśāt sūryādyā

bhavanty aty-ugra-tejasaḥ

yad-aṁśena dhṛtaṁ viśvaṁ

sa kṛṣṇo daśame ’rcyate

From Lord Kṛṣṇa’s potent energy even the powerful sun gets its power, and by Kṛṣṇa’s partial expansion the whole world is maintained. Therefore Lord Śrī Kṛṣṇa is worshipable"

Srila Prabhupad in purports of 10th Chapter.

Although Arjun knows this but for the benefit of common men he is asking Lord to reveal the general process by which the all pervading Lord can be understood by common man. When one realise the God is so great great so great that I am too much small...then he surrender.

Now in Chapter Nine the glories of the Lord will be delineated. For those who understand that Krishna is the Supreme Personality of Godhead, the pure and transcendental Personality, these chapters will be very beneficial. Here Lord has clearly explained his different energies to establish devotion in firm conviction. Here the word Rajvidhya refers to pure devotional service which consist of 9 different activities in relation to Supreme God Vishnu viz hearing, chanting, remembering, serving, worshipping, praying, obeying, maintaining friendship and surrendering everything.

Now, starting with the Thirteenth Chapter, how the living entity comes into contact with material nature and how he is delivered by the Supreme Lord through the different methods of fruitive activities, cultivation of knowledge, and the discharge of devotional service are explained. Although the living entity is completely different from the material body, he somehow becomes related. This also is explained. He also explained the process of knowing the knower of the field of activities.

"The knowledge explained in this chapter is proclaimed by the Supreme Lord to be superior to the knowledge given so far in other chapters. By understanding this knowledge, various great sages attained perfection and transferred to the spiritual world. The Lord now explains the same knowledge in a better way. This knowledge is far, far superior to all other processes of knowledge thus far explained, and knowing this many attained perfection. Thus it is expected that one who understands this Fourteenth Chapter will attain perfection." In this Chapter Lord Krishna also declares him to the father of all whatever may be.

Therefore one should take it very seriously that devotional service as described in the Twelfth Chapter is the only way to get out of this false representation of the real tree( Banyan tree with roots up and branches down)

The process of breaking attachment to the material world is discussed in the beginning of this chapter. In this chapter the first five verses describe the process of freeing oneself from these weaknesses of heart, and the rest of the chapter, from the sixth verse through the end, discusses puruṣottama-yoga. It is explained in this chapter that the purpose of Vedic study is to understand Kṛṣṇa. Therefore one who is in Kṛṣṇa consciousness, who is engaged in devotional service, already knows the Vedas.The tree of this material world has no end, and for one who is attached to this tree, there is no possibility of liberation.

Check Bg 16.9-16.16 shloka on 6th minute. In the Sixteenth Chapter, it is concluded that one who does not follow the principles laid down in the scriptures is called an asura, demon, and one who follows the scriptural injunctions faithfully is called a deva, or demigod. The title of the chapter is " Divine and Demoniac Natures".

The conclusion of full Bhagavad-gītā is stated in the Eighteenth Chapter in 66th Shloka. Although the rituals of religion are confidential, meditation and cultivation of knowledge are still more confidential. And surrender unto Kṛṣṇa in devotional service in full Kṛṣṇa consciousness is the most confidential instruction. That is the essence of the Eighteenth Chapter. As in the Second Chapter a synopsis of the whole subject matter was described, in the Eighteenth Chapter also the summary of all instruction is given. Devotional service in Kṛṣṇa consciousness is the sign of liberation from material entanglement, and this is explained in the Eighteenth Chapter. symptoms of life, according to the different modes of material nature, are described in the Eighteenth Chapter.

This chapter states that anything done without the transcendental objective – whether it be sacrifice, charity or penance – is useless. It defines types of food, donation, worship, donation as per 3 modes. It also describes penance of body, speech and mind. It describes how to perfect yagya and for whom one should do sacrifice.

This chapter lays the foundation into the circumstances which led to Shri Krishna speak Bhagvad Gita knowledge. Induction of the circumstances leading to Gita knowledge as part of Gitaji lays the principles of acknowledging the support of those who takes you towards spiritual world. The impact of this chapter as mentioned in Gita Mahatmay of Padam Puran is that there is no qualification for reading and hearing this chapter. Whoever hears it or reads it regularly and daily will get his/ her heart fully pure irrespective of hearer being human or any other living being. Mentioned are the important names involved in both parties and the different grades of family relations whom Arjun was supposed to kill. It also mentions the process of how a family lineage get degraded and how we can save it. At the end it shows how Arjun was extremely soft hearted and kind and hence lays the eligibility for receiving self knowledge.
