We are here for very specific reasons. we have nothing to lose and everything to gain. we are in the realm of desires and its our desires and craving that brought us here and that brings us suffering over and over again.
You dont have to reject anything or isolate yourself from anything but its indeed about purifying your self to discover your inner self which is happy, at all time and joyful. the way to purify yourself is by letting go of some negative behavior we all have. We have to reduce the egocentricity, the me, the judgments and thoughts about the world. especially letting go of hate, ill will, negative thoughts and unwholesome desires as most of what we think is not absolute truth, its only a view point based on our limited understanding and view of the world yet we believe what we think, and that is the problem as our negative thought makes us suffer.
Any negative thought makes us suffer, yet we dont see it and we continue to justify our negative thought, ect.
Everything we need is right in this moment, but our mind doesnt allow us to see it because we are lazy, dont want to put effort (in trying to purify ourselves with mindfulness) and we accept ourselves to sensual desires, hatred, torpor, restlessness and doubt even though we know it doesnt bring any real satisfaction in the long term we still continue to think and act and believe what the mind think and justify the unwholesome thoughts and actions he makes. Its all just a band aid and not a good and safe remedy.
You dont have to learn to not be part of this world, not at all! its about learning to be in this moment, fully aware of whats actually there and dont allow the mind his unwholesome tendencies which are the 5 hindrances which are absolutely detrimental to one's own happiness.
There is nothing to become, we are already everything we want and have everything we need in this moment, but we cant see it only because we cant let go of our judgements, hindrances, our thoughts, our desires and our egocentricity.
again, I highly suggest anyone interested if only for general information to hear a monk talk about exactly what Im talking about. she is much more interesting then me

doubts are greatly reduce when one actually try to meditate and is able to concentrate, even for 10 seconds. you can only concentrate with a happy mind, hence why its really needed to learn mindfulness of thought and integrate in our life.
when there's no thought in the mind, in concentration, this experience shows the mind that concentration do bring another type of calm and satisfaction and happiness that is obviously better then the way we've learned to gain happiness thru our senses...
