The third law of Newton states that "every action has opposite reaction. The theory perfectly implying in our daily life through the conduct of Karma. Karma, meaning "action" or "deed" in Sanskrit, is a crucial concept in Hinduism, Buddhism, and other Eastern traditions, emphasizing the law of cause and effect. It highlights the importance of responsible living, encouraging individuals to consider the consequences of their actions, both for themselves and others. By understanding karma, individuals can strive to cultivate positive actions and attitudes, leading to a more fulfilling and meaningful life. To highlight its effect on current life and life after death, Sanskrit has following verses :
यथा धेनु सहस्त्रेषु वत्सो विन्दति मातरम् |
तथा पूर्वकृतं कर्म कर्तारमनुगच्छति ||
Yathaa dhenu sastreshu vatso vindati maatram
tatha poorvakrutam karma kartaarmanugachchti'
Yatha = just like.
Dhenu = cow
Sahastreshu = among thousands
Vatsa = calf of a cow.
Vindati = reaches, locates.
Maatram = mother
Poorva = earlier one.
krutam = done
Karma = a deed.
Kartaar = the person who has done an action.
Anugachchti = follows.
i.e. Just like a calf locating its mother in a herd of thousands of cows, the 'Karma' done by a person in his previous birth follow him in his present birth.
According to the concept of "Karma". all actions, good or bad, done by a person during his life time are called Karma, classified further as Sukarma i.e. good deeds and Kukarma i.e. bad deeds. The results of these karmas fructify during ones' life time or follow him in his next birth.
So if a person has done 'Sukarma' in his previous birth he gets the benefit of those karmas in his present birth. Similarly if a person does 'Kukarma' in his present birth, he may get its result during his lifetime or in his next birth. It means that fate of a person reaches him in his lifetime or in the next birth, just like a calf locating its mother in a herd of thousands of cows.
