There is a beautiful and convincing explanation.
Thumb represents your Parents
Second (Index) finger represents your Siblings
Middle finger represents your-Self
Fourth (Ring) finger represents your Life Partner
& the Last (Little) finger represents your children
Firstly, open your palms (face to face), bend the middle fingers and hold them together - back to back.
Secondly, open and hold the remaining three fingers and the thumb - tip to tip.
Now, try
to separate your thumbs (representing the parents)..., they will open, because
your parents are not destined to live with you lifelong, and have to leave you
sooner or later.
Please join your thumbs as before and separate your Index
fingers (representing siblings)...., they will also open, because your brothers
and sisters will have their own families and will have to lead their own
separate lives.
Now join the Index fingers and separate your Little fingers (representing your children)...., they will open too, because the children also will get married and settle down on their own someday.
Finally, join your Little fingers, and try to separate your Ring fingers (representing your spouse).
You will be surprised to see that you just CANNOT....., because Husband & Wife have to remain together all their lives - through thick and thin!!
