Hari OM Kamalji, Pranams.
I just posted those verses (Sorry about that. Should have done that before). Now you will be able to see that those are the verse numbers from Chapter 1 that Holy Gita Ready Reference book recommends for us to memorize. Regarding your question about Significance of memorizing those 4 particular verses - HGRR doesn't give those reasons in the book. In my understanding the reasons are below -
Verse 1: First verse of Gita. First word and and the last word of Gita are important because put together they become "Mama Dharma" (My Dharma). Also this is the only verse which Dhritarashtra gives out. Rest of the stanzas are Sanjaya's report. This verse clearly shows Dhritarashtra's love for his own children was way greater than nephews. So it brings out the 'root cause' of why war happened and who sowed the seeds of confusion in Arjuna.
The rest of the verses show BEFORE and AFTER pictures of Arjuna.
Verse 21 gives Arjuna's BEFORE picture. It shows that Arjuna was eager to start the righteous war. It shows Arjuna displaying daring, chivalry, great courage and firm determination. He calls Krishna as Achyuta means “One who does not abandon his stand" Hrishikesha means "Lord of the senses". So we can see here Arjuna was very composed and was in total control and very eager to start the war before seeing enemy lines.
Verse 29 and 30 give Arjuna's AFTER picture.
Here 'Anxiety-state-neurosis' kicks in, in Arjuna. We see in verse 29 all the physical symptoms of that manifesting. In verse 30 we see mal-adjustment displaying at his mental level. He is not able to stand and the bow literally slipped from his hand so obviously he was in no position to fight. A very dramatic change takes place. From "war ready Arjuna" he turns to "Grief stricken" Arjuna.
So these verses give root cause and the bird eye view of "Arjuna's grief" which was the theme of this chapter.
Pujya Gurudev said in one of his discourses on Gita that when a jeweler wants to display his brightest diamond he selects darkest background to display it on. Chapter 1 sets that most dramatic background by creating a toughest and most challenging situation one can ever imagine. Reading that we think "my situation is nothing compared to Arjuna's situation. My mental state is not so broken as Arjuna's. If Arjuna could recover and face challenges by listening to Gita, I should be able to come out of my challenges by studying it !" I think is that is the purpose of this whole chapter.
This chapter was really for us to reflect on our own negativities and challenges. Next chapter is about learning and then assimilating great truths of Advaita, so our study focus and the way we approach it, will be little different.
I suggest everyone ...if you have attended discourses of Chinmaya Mission Acharyas or have access to Chinmaya Mission Acharyas' discourses/notes, this will be a good time to look for them, listen to them and keep that material handy. We will be studying and taking in a lot of knowledge in chapter 2 and I hope you all share generously with others.
And what are we discussing about memorizing? Are these the verse numbers of Chapter 1? Kindly explain.
And what is the significance of memorizing only these 4 verses in particular?
