Transcript of Bhakti-Shastri class on this verse by Chaitanya Charan

Now Krishna concludes this chapter by another superlative emphatic verse

Bg 15.20

iti guhya-tamaṁ śāstram
idam uktaṁ mayānagha
etad buddhvā buddhimān syāt
kṛta-kṛtyaś ca bhārata

Synonyms: 

iti — thus; guhya–tamam — the most confidential; śāstram — revealed scripture; idam — this; uktam — disclosed; mayā — by Me; anagha — O sinless one; etat — this; buddhvā — understanding; buddhi–mān — intelligent; syāt— one becomes; kṛta–kṛtyaḥ — the most perfect in his endeavors; ca — and; bhārata — O son of Bharata.

Translation: 

This is the most confidential part of the Vedic scriptures, O sinless one, and it is disclosed now by Me. Whoever understands this will become wise, and his endeavors will know perfection.

iti guhya-tamaṁ, so guhya is secret guhya-tamaṁ is most secret this is the most secret knowledge among the Shashtra, so vedas talk about so many other demigod but there ultimate purpose is to direct towards Krishna and this is confidential,  iti guhya-tamaṁ śāstram, Bhagvatam describes that when Brahma Ji studies the vedas what happened is first time when he heard it he thought that conclusion is Karma Kanda, second times when he heard it he thought the conclusion is Jyana Kanda, third time when he heard it then he understand Oh the conclusion is Bhakti. iti guhya-tamaṁ śāstram, and what is confidential? That Krishna is Purushottama and He is the goal of the Vedas, idam uktaṁ mayānagha, I have spoken to you because you are ānagha, non-envious, as Krishna also explained in 9th chapter Edam Tu Te Guhyataram Pravakshami Anusuyave, very confedential knowledge I am going to speak to you because you are non-envious, 

etad buddhvā, one who knows this

What happens?

buddhimān syāt, such a person becomes truly wise, buddhimān

kṛta-kṛtyaś ca bhārata, such a person whatever action they will do they will attain success.

Purport: The problems of material existence are due to these weaknesses of the heart.

Which means instead of serving for Krishna we give up for lower desires. 

But by praying to Krishna and by solidifying our connection with Krishna whenever we have facility to then we become stronger and stronger and then this weakness of heart will overcome, and then instead of enjoying separate from Krishna we wanted to serve and love Krishna. 

Chapter Summary:

So in this way the chapter Purushottam Yoga starts from Banyan tree which means detachment over there 

then talks about without detachment one has to continue the cycle of birth and death 

and therefore one has to have Jyana Chaksu 

then what happens if someone doesn’t have Jyana Chaksu 

so from 12 the verse it says see the hand of Krishna even at material level, and then see the hand of Krishna trying to liberate us from material existence then Jyana to Bhakti is most beautifully illustrated in tri sloki where Vedanta is explained how it leads to devotional conclusion, 

and then understanding that Krishna is the highest reality and Bhakti to him is the highest sadhana.
