What are the useful things when necessary arises ?

In  the Vedic Scriptures and the other classical texts it is explained  many alms and theorems about the life for the ultimate happiness to all . We know in our lives, suppose if we deposit some money in the Bank, that amount will be useful in future for our necessaries. Like that if we protect the things and life that is more useful in our future lives.

Here, we can see, suppose, if the money is saved or kept in  a virtuous man, that money can be got back without any loss. Because, that  man has virtues which he does not do any deceipt or does not do any perfidy to the other person. Hence the money is safe to get back. 

The children who are begotten in the early age will be benefit at the right time  to us. The benevolence which we do to others will be more useful to us in future for the necessary. If we are educated at the right time and the education which we have is most useful in our lives for our livelihood. Hence if think why the above useful things give most happiness and peace to all of us, certainly we can accept there is truth in that theorems.
