Let's say there are two individuals A and B both destined to lose a loved one at a given point in life due to past life Karma. Now both can feel differently post this event. A can feel sad, dejected etc. while B can brush it off. So my first question is whether past life karma also plays a role in shaping our gunas pre/during/post event? If so, then is the corollary that as A's sin in past life was of higher magnitude than B, he feels the suffering more than B ?
Now I understand that in a given life gunas change with time (more like certain aspects of gunas are more prominent). Also, we can change our gunas in a given life through penance, austerity etc. Will this act of changing gunas be considered part of Kriyamana karma ?
