Deaths and Marriages - the confluence points

recently my mamaji died of a heart attack in surat.. i visited there with mummy and papa when they came from azm and again alone for the 12th day puja rites.. thr i happen to meet all my maternal uncles, aunties, sisters, brothers etc, whom i haven't met for years.. i realised that now people meet when there are big things happening around... and 2 big things which stick out are marriages and death.. these 2 things symbolise unification.. one shows unification of two souls whereas other leads to unification with god..
