Selfish or Selfless - What is true altruism?

I have often been alleged to be too selfish, right from my adolescent years, not sure if it goes back to my childhood days. Such allegation, especially from close friends and family often troubled me and always perplexed me, because..I just happened to do what I wanted to..and did not know how to act any differently without the act itself becoming pretentious, something I was not too good at. A so called selfless attitude as I witnessed it perplexed me even more...because I found selflessness a mere extension of selfishness. Where you did something for others to gain something yourself, even if it was just reinforing the belief in your selfless nature. I knew of people who had dedicated their lives to service say that they did so because they though that was their way to reach God or whatever. Maybe the act by itself is honourable but my young mind wondered how the motive was any different from a selfish one - 'I want to reach God'.
It was not until I met Guruji that I understood what is service. Guruji says it is good to have a ego...just make it so big that it can encompass the whole world. And Guruji is an example of that, making the whole world his own. Selflessness is nothing except the boundary between two separate people disappearing. As long as you recongnise a boundary and do something for the other, you are still being selfish, in some way or the other. When you are truly selfless you don't know you are, because you don't recognise the 'other', like a mother doing something for her child..one would not call that selfless...just natural. Such is true selflessness, when such oneness exists with all.
I remember the day when Dia was born. I understood the love that I shared with all. For no reason, with no condition, with no expectations I was helplessly in love with this tiny baby lying in my arms. I saw the whole world reflected in her, and for a moment felt the same connection with everybody on this planet.
On a lighter note, there was a day I had this massive craving to have an ice cream. I went all the way out to a nearby store, bought this ice cream that I really loved and walked out, eager for the moments of bliss. A small beggar child approached me and tugged at my dress for the ice cream. I found myself giving the ice cream to her very naturally and then turned back to buy another one for myself. And I suddenly discovered that the desire was no longer there. The desire that had brought me out of my home, made me walk up the street somehow got satisfied with the beggar child enjoying the ice cream!
In Guruji, there is no self at all. He is just a reflection of our selves. Whatever we are, He just mirrors it.
