How do you survive in the world with this understanding?
It's real simple. You keep this understanding as close as possible, close as in always remembering it, bringing it into your life as much as possible. I have many nicknames and many functions, such as father, friend and so on. These remind me that 'I' am not a fixed enitity and can be viewed on infinite levels with an infinite amount of minds observing 'me'.
You have become more fluid because you are lessening your grasp on who you 'think' you are and becoming more who you are, naturally. So your experience becomes more fluid like, more accepting.
Where do you go now?
I'll answer this with a question: Everyone experiences their own world. We all experience different worlds. Who created your world and where does it come from?
Living or joining a small Sangha community is very fortunate. They can function on many levels, these special friends can help you live more freely in the world, you dont need to give up anyone or anything else if you do not wish to. Your progress is at your pace. You can still function in world in exactly the same way, what is different however is your attitude towards it. A very famous saying is 'remain natural whilst you change your aspiration' meaning you dont need to shut yourself away or wear funny clothes or appear differently to others. What matters is that you change your mind and aspirations and cultivate positive intentions.
I work in an investment bank. What i say to you is that it doesn't really matter where you work to some degree, it's what you do with your mind that matters. I know many people who work in care and helping others, of course this is conducive to a meaningful life but if you understand your mind well, you will always be creating happiness wherever and whatever appears to your mind. Your real passion is for being free and living a happy life that others can also enjoy. You need to create this life. You create this by using whatever appears in your life in the most positive way.
how do you function and work in this modern society with your beliefs??
I function and work in this modern world the same as anyone else with the added goal of being happily engaged in training my mind using methods that work and whatever appears to create a better world for myself and others.
People will relate to the person they see 'in you'. This isn't you they see. Try not to feel discouraged when others dont see you as you see you. This will induce security because we are so used to believing that what others think of us is of paramount importance in obtaining happiness for ourself. This is called attachment. We project happiness onto people and what they think of us, from within our own mind, and so we are deceived by it all most all the time. Not many people understand this.
People you are closest to or who you respect, their opinions will matter more to you. You expect more from them. How you see them will determine your progress - They are great aids in helping you overcome the attachment to what other people think of you. They reflect much subtle mind sets you have been trapped into, like mirrors they illuminate the painful states of your mind. How kind they are.
