what exactly is spiritual growth?

We lost our broadband connectivity some time back and that is the reason behind the gap between blog entries. Over this period of time, I read some very interesting books and tried some novel methods to remain centred and to be present in the here and now. And then last week, I ran into Tertium Organum by P D Ouspensky which has forced me to do a quiet evaluation of what ever I have learnt over this life. What an amazing book !!!! It does not spoon feed the reader but leads him on to a stupendous journey and then leaves him exactly at the right time so that the reader can explore things on his own. The book is simply ingenious as it marries mathematics to inner awareness. As of now I am still trying to understand the 4th dimension and the nature of time. It is taking a lot of time but for a change I really want to do it slowly. The more I think about them, the more nuggets of wisdom I extract.
Come to think of this, is this really some kind of growth for me? can i call it spiritual growth? or is it just another lesson that i need to learn before life introduces me to another set of challenges? All my life, I have witnessed this fact, that life would present me with a set of challenges and once I have learnt my lesson and am ready for next set of challenges and am willing to face the next set, my life would go topsy turvy and I will find myself in another context. Initially I was very jealous of simple minded people who learn one set of challenges and who live in the same context, day in day out. When I tried this out, I started festering. My life almost became meaningless. And so I was forced to make changes and move on. And now I am here, learning some new lessons. But now I am not impatient for the lessons. That was one of my learnings :-)
Recently I started watching Roadies 8 and it is indeed a different concept. So far it has been enjoyable. There was a guy A. in the group who was really very loud, very boisterous, very abusive, politician kind of guy. He reminded me of many such characters who I had the misfortune to meet. For A., though, the comeuppance was swift. He has been kicked out of the game. Sometimes, I would marvel at the foolishness of such people. Do they really think that they can somehow keep on fooling people all the time? I don't know. Recently I have stopped believing in the causes and effects theory. Things happen, just like that. And one has to accept it and keep moving on. Retribution for the mess can happen or can not happen. That is not in my control. But my thoughts and emotions are in my control and I will choose to turn my back on such unsavoury people.
