Kriya Questions (4479 pranayama)

[Magnanimous]

Hey since starting Kriya 3 months ago and completed 4479 pranayama, I've accumulated some questions through practice, reading, and thinking about the future.

• I want to move close to the clubs at Vegas and Austin one day. Those areas are known for being super noisy. So if I move there, would it be ok to upgrade from earplugs to noise cancelling headphones, as long they aren't too distracting (eg weight)?
• I once read that it doesn't matter how many pranayama reps you do, as long as you can do them properly. Instead of doing them just set a timer and just do pranayama. Why just a timer instead of rep counting?
• How long does it actually take to master the specific pranayama technique you are doing? I heard it took a year. I'm steadily getting better but I think I won't be fully done at 10,000. Some small imperfections each pranayama, but after the larger part of routine I'm getting more aftereffects with serious peace, joy, love, that persist for a couple hours. 
• What factors affect the happiness from Kriya other than the quality of technique execution and time of the routine itself? ie what factors in daily life.
• In Parvastha I heard you're meant to "concentrate like a motherfucker." But how does this reconcile with concentration as an effortless "Being" Santata Gamana recommended. Also when I concentrate that hard its harder for me to generate the happiness which usually comes from Parvastha since I'm so locked in. How do I concentrate that hard and still attain a high yield Parvastha state that persists for a few hours?
• This one time in Paravastha I was focusing on my Being when my focus drifted to external objects, then I had this chain of logic in my head. I heard Being isn't able to be fully communicated in words but it goes along these lines: You are everything, because since you, the awareness, can place awareness on other objects, there isn't actually a distinction between you and that object. (Logic inspired by an enlightenment exercise I read in the past) Is that correct?

 

I am extremely thankful for starting Kriya Yoga. After practicing, sometimes it has given me amazing feelings of peace, joy, love, and bliss I can feel throughout my entire body, which will only become stronger and more frequent as I can continue, and I can train to maintain it throughout the entire day. Being is much easier to access. Nature is supremely beautiful. In Parvastha I have these interactions with my consciousness that make me just know I'm making spiritual progress like never before.
