The last year I've been meditating very little, due to having my autistic son (seriously autistic) at home. What I can say is that I feel the lack of lengthy meditations.
We all have various paths to God. Yours sounds much like karma yogi. I bet you and your son would really enjoy spending time together seeing Amma for a retreat next time she comes to Italy. I’ve seen many adults with others they are in care of at her events. Amma delights in meeting exceptionally challenged and different human beings. I have personally witnessed this in individuals I’ve seen receiving darshan before me. I think the two of you would find mutually satisfying spiritual activity there!
Choose a path that benefits others and serve with selfless love ~ Amma
