First of all, I'd just like to say that I think U.G. Krishnamurti is Awesome. Very Zen. I love that about him.
Karma simply means action. It sounds like UGK was responding to the question "how does one act in the world?" And he said something to effect of "responding to everything out of fear does not even count as acting in the world. It's not living. It's a shallow, hollow, miserable existence." (he's kind of an intense guy
) In other words, he's saying the only action worth anything (i.e. the only REAL action) is acting in a way that is not fundamentally out of a sense of fear.
I don't know UGK's relationship to pain exactly (I mean, how could I?), but I, personally find that when the relationship is so different to the sensation that it's not being blocked, it's not experienced the same way. In other words, pain is, by definition, just more awareness that is being blocked by fear. Without the fear, it's just more awareness, the need for attention to be there.
In terms of purpose, basically he was making fun of those that take the idea of purpose seriously, trying to make everything into something overly dramatic. Of course life is deeply meaningful on one level, but it's truly amazing how many seekers get caught up and lost in that sort of thing. Having a flippant response can certainly end that detour quickly.
Saying that those who are not Awake do not see things are they are is a teaching tool. Objectively speaking, the truth about that statement is one or more of the following:
a.)It's true
b.) It's not true
c.) It's neither true nor untrue.
d.) Both are true.
e.) None of the above.
I think, if given the test on an exam, I would go with e.
Anyway, those are my interpretations and opinions on the matter.
When did I say that I enjoy food more and more each time? I don't remember saying that.
I enjoy experiences a lot more in the sense that I appreciate them more, but also there is less and less contrast between the enjoyment gotten from something and the enjoyment from just being.
Also, there is less and less need to use whatever it is to "fill the fulfillment hole" and so the need for it starts to drop off pretty quickly.
In terms of sex, I'm not to worried about conserving my energy. What does conservation of Energy have to do with Enlightenment anyway? Interestingly, enough the energy has been going up my spine so intensely that there is no loss of energy for some reason. That's not intentional (as I don't really worry about it), but it IS starting to happen. Go figure.
There are many schools of thought on how abstaining from sex increases spiritual potency. While I've noticed this to be true on some level, there are a lot of things one can do to help make the truth clearer, including (but not limited to):
a.) becoming vegetarian
b.) abstaining from sex
c.) doing regular cleanses
d.) eating healthy
e.) getting enough sleep
f.) getting up early
g.) meditating
h.) doing regular excercise
j.) yoga
k.) affirmations
l.) abstaining from drugs
m.) abstaining from alcohol
n.) not eating processed foods
o.) going vegan
p.) praying to God/Goddess
q.) reading mystic literature
r.) bathing a lot
s.) being devoted
t.) hanging out with Enlightened people
u.) visiting saints
v.) self improvement
w.) exploring your demons
x.) receiving "healings"
y.) chanting
z.) being nice to people
and the list goes on and on and on. You see my point?
Will they help you get Enlightened? Who knows? Maybe. Are they a requirement? Not necessarily. If you are listening to yourself, you will spontaneously do what you need. I, personally, stopped drinking alcohol. That was what I needed to realize the truth, and it happened spontaneously. Is that true for everyone? Of course not. There no one right thing or way for everyone, or everyone would just do that, get Enlightened and be done with it. It cannot be limited by that sort of thing.
