I lost my father in 2014 and that is when I really started digging into the spiritual aspects of Father's day!
The father may be present (if you are lucky) or absent..but we still carry our father within us, in our DNA, in our genes ..and this is a scientific fact...We inherit many things from our parents,grandparents... our body, many features and even behavioral characteristics, our strengths and weaknesses...it is just amazing how much we are connected with our forefathers!
In spirituality, it is lot more involved than just genes and DNA...it is said that even our mind and soul are deeply connected with our parents, grand parents etc.. Many cultures even have the practice of giving a grand father's name to a new-born child, as there is deeply held belief that these soul groups reincarnate in the same family, again and again.
In India, we have this practice called Tarpanam, an offering made to ancestors! This is a ritual which can often produce dramatic changes in one's life with a small investment in time. Serious life situations in finance, health and relationships have dramatically improved after performance of these rituals...
This is very different from sitting in meditation trying to grapple with the mind...While performing ancestor rituals, there is a natural connection, love and emotions involved, greatly helping the process. Ancestor rituals are typically a case of "mutual help" ...see notes below.
We will revisit the topic of ancestor rituals and how they can help our life situations at a later time. The only point I want to make now is that taking care of one's aging parents (including father) is of immense importance not only from an ethical standpoint....From a spiritual standpoint, once that person leaves the bondage of the body, that spirit gets the abilities to know and control some of our destinies as well.
