The motivations i have recieved are not so much in the practice but rather in the spiritual experiences that happen in life's day to day activities. If we look for a logical sequence of events it just doesn't always appear forthcoming like 'a' produces 'b'. This may b one of the impediments we experience in placing a criteria for sucess on spiritual progress. We may have to evaluate it differently.
Since I'm still practicing haung sau and kryia of course I don't give vital importance to stopping the breath and plunging into superconsciousness.
But it would be a definite boost.
No doubt u know the story of Anandamoy asking P.Y. when he would have a similar experience and he answered 'soon now soon'. I also remember a similar story about Amma. A devotee always asked when she would get a spiritual name. Her response was always 'tomorrow'. i also remember her saying that 'even in heaven we have to wait in que.' And Anandamoy said ' I was always this way ' .... pointing to himself. Yes, no doubt we would get a boost but how many of us would think instead... how best we could serve?
I know for me; meditation, from the beginning, was all about me. It took a long while to even realize that.... How selfish i can be. Superconsciousness and Selfishness are like oil and water - they don't mix. Looking at the lives of say an Amma we quickly realize our idea of service is at best only the beginning. I have seen this in saints i have met. They have that one thought of serving the Lord. It is truly humbling when we are blessed to see their service in action. Whenever I have difficulties meditating i start looking at how much I have served lately. In many ways are journey has only begun. Attitude adjustment is also a part of our every day routine. But as soon as we are sincere we will be given many opportunities to see where we fall short. Perhaps yours is much different then mine.
