Bhagavad Gita Verse 46, Chapter 2

yaavaanaartha udapaane sarvathaha samplutodake |
taavan sarvheshu vedeshu braahmanasya vijaanataha || 46 ||
 
Just like there is no use for a well when water is flooding everywhere, so does a brahmana know all the contents of the Vedas.
 
yaavaan : just like
aartha : use
udapaane : well
sarvathaha : everywhere
samplut : flood
udake: water
taavan : similarly
sarvheshu : everything
vedeshu : contents of the Vedas
braahmanasya : a braahmana
vijaanataha : realized
 
In the last shloka we asked a question : if we were to reduce our dependence on worldly things, wouldn't we have to give up TV, music, games, parties etc. Wouldn't that be a boring life?
 
Think about your childhood. All of had a craving for toys when we were kids. But there came a stage when most of us outgrew toys because we began to think about higher things like career aspirations etc. So all toys began to look the same to us, regardless of the price, shape, size, colour, brand etc. , from a simple spinning top to an expensive model airplane.
 
Similarly, Shri Krishna says that once our thoughts become high quality, i.e. they pertain to our svadharma and to spiritual contemplation, then automatically we will begin to feel less need for any external entertainment and enjoyment.
 
Therefore, this shloka says that one who always maintains equanimity will have known all there is to know about the material world, and will begin to transcend worldly matters and knowledge.
 
In this shloka we notice that the word "braahmana" appears. Braahmana here does not refer to the caste system meaning. It refers to an individual who is always contemplating about brahman, which is nothing but the eternal essence that we learned about in the early part of this chapter. Also the word Veda, like in previous verses, refers to worldly knowledge.
 
Now, the two techniques prescribed so far, reducing unnecessary thoughts and improving quality of thought, were preparatory techniques. They are meant to prepare us for learning the main technique of the teaching, which is covered in the next shloka. It is probably the most famous and oft-quoted shloka in the Gita. We shall cover it in great detail.

Bhagavad Gita Verse 19, Chapter 2

ya enam vetti hantaaram yachshainam manyate hatam |
ubhau tau na vijaanito naayam hanti na hanyate || 19 ||
 
A person who believes that it (the eternal essence) slays, and another who believes that it is slain, neither of these understands. It does not slay, nor is it slain.
 
yaha : that person who
enam : this (body dweller)
vetti : believes
hantaaram : slayer
yaha : that
cha : and
enam : this
manyate : believes
hatam: slain
ubhau : both
tau : those
na : do not
vijaanitaha : know
na ayam : this does not
hanti : slay
na hanyate : nor is slain
 
The "It" in this shloka and the following shlokas refers to the body-dweller. Here Shri Krishna addresses another concern that Arjuna had raised. Arjuna thought that that he will be held responsible for killing his kinsmen, which was something that was abhorrent to him. But Shri Krishna through this shloka advised him to use the logic or the perspective of the eternal essence. The eternal essence does not kill, nor does it die from someone else trying to kill it.
 
But how does this apply to us? We are not warriors, and it is rare that we will be put in the position of killing somebody. So there must be another interpretation.This shloka equates the act of slaying to performance of any action, and being slain to any change or modification. In other words, the eternal essence never performs any action, nor does it undergo any change or modification.
 
As an example, let's consider at the sun. Without the sun there will be no activity or life on this planet. There would be no plant life because plants use the sun's energy. There would be no animal or human life because both cannot survive without plants. But, does the sun perform any action pertaining to growing a plant or an animal? Does it get affected by all the changes happening on earth? It does not that that "I caused this forest to grow" or "I was impacted by this eclipse". It remains actionless and changeless.
 
The shloka goes on to say that one who thinks that the eternal essence acts or kills is not using viveka or discrimination, and that person does not have the correct understanding. The person is still thinking at the level of the material object, or in other words, the level of the un-real, and has still not learnt to discriminate between the two.
