Having a controlled mind will help build best practices in day today life. Controlled mind means controlled body. Some of the involuntary functions are not a part of our controlling mechanism.
Remembering the person who is dead.. we only think about their actions and their deeds while they were living on earth. Emotions, health, dependency, thinking, relationships, finance, love, attachment are all a part and parcel the karmic cycle and life. Having a control over various ingredients of karma will help us :
- kama — lust
- krodha — anger
- lobh — greed
- moha — delusory emotional attachment or temptation
- mada or ahankara — pride, hubris
- matsarya — envy, jealousy
The above gives a complete understanding of the Arishadvagas that are pre defined in the Hindu theology.
When we die, what happens? No one knows. What we know is that we did something good and something wrong if we have the ability to think during our death.
By reading the patterns of lifestyles and actions from the dead, evaluating their outcomes and remembering them for what happened with them helps us lead a life based on past history (along with technological advancements and other factors) and incorporate our lives with a sense of understanding that this life has a meaning and the purpose has to be explored.... What is wrong in one's eyes is right in other's !
