Karma Of Present And Past Birth

At my place, there was an aunty age of  74. She was very humble and spiritual. The uncle passed away earlier of heart attack. Few years ago, her daugther passed away by accident after completed medicine and came back from India. Then her son passed away by accident too. Later she spend the rest of her life in spritual path and help others. Last week she was killed in her home by some burglars. On the other hand, there was a guy who have done almost all vice known to man till the age of 73 and passed away by heart attack too.

Does the life of the both person above is based on karma? Does people enjoy happy life and punished according to their acts no matter at present or past birth?

KARMA

Karma in Hinduism is also considered to be a spiritually originated law. Many Hindus see God's direct involvement in this process; others consider the natural laws of causation sufficient to explain the effects of karma.However, followers of Vedanta, the leading extant school of Hinduism today, consider Ishvara, a personal supreme God, as playing a role in the delivery of karma. Theistic schools of Hinduism such as Vedanta thus disagree with the Buddhist and Jain views and other Hindu views that karma is merely a law of cause and effect but rather is also dependent on the will of a personal supreme God. Examples of a personal supreme God include Shiva in Shaivism or Vishnu in Vaishnavism. A good summary of this theistic view of karma is expressed by the following: "God does not make one suffer for no reason nor does He make one happy for no reason. God is very fair and gives you exactly what you deserve."

Karma is not punishment or retribution but simply an extended expression or consequence of natural acts. Karma means "deed" or "act" and more broadly names the universal principle of cause and effect, action and reaction, that governs all life. The effects experienced are also able to be mitigated by actions and are not necessarily fated. That is to say, a particular action now is not binding to some particular, pre-determined future experience or reaction; it is not a simple, one-to-one correspondence of reward or punishment.

Karma is not fate, for humans act with free will creating their own destiny. According to the Vedas, if one sows goodness, one will reap goodness; if one sows evil, one will reap evil. Karma refers to the totality of our actions and their concomitant reactions in this and previous lives, all of which determines our future. The conquest of karma lies in intelligent action and dispassionate response.

One of the first and most dramatic illustrations of Karma can be found in the Bhagavad Gita. In this poem, Arjuna the protagonist is preparing for battle when he realizes that the enemy consists of members of his own family and decides not to fight. His charioteer, Krishna (an avatar of god), explains to Arjuna the concept of dharma (duty) among other things and makes him see that it is his duty to fight. The whole of the Bhagavad Gita within the Mahabharata, is a dialogue between these two on aspects of life including morality and a host of other philosophical themes. The original Hindu concept of karma was later enhanced by several other movements within the religion, most notably Vedanta, and Tantra.

In this way, so long as the stock of sanchita karma lasts, a part of it continues to be taken out as prarabdha karma for being experienced in one lifetime, leading to the cycle of birth and death. A Jiva cannot attain moksha until the accumulated sanchita karmas are completely exhausted. - wikipedia

There is millions type of flower around the world. Each flower has its own specialty. There will be no one in this world who could hate flowers.
Flowers are symbols of beauty, purity, freshness, fragrance and exct.exct. Flowers use to many purpose such as decoration, thanking someone, appreciating someone, for prayers and all of it are positive events. Wherever there is any good events there will be flowers. And flowers is the only object that is very close to God's statue/symbols at  all temples or praying places. Jasmine, hibiscus,daisy,lily,olive,white rose, red rose, sunflower,violet, and no matter what it is called..... it is a flower.
And that is how human are categorized. Humans are differ with their own color, size, and appearance but humans are humans (spiritual person call it as souls).
Each humans are special according to their own skills and by their physical aspects. There is no such thing as  hibiscus is low class and jasmine is high class or low class white rose and high class red rose. Same goes to human, we are created to be differ might be for some positive purpose and not for one human take advantage on another by discriminate them, that is negative. In another way the positive purpose that we are created might be not achieved by doing this. Well, the same physical look like humans divided within them is cause by caste, hence the power and the skills own by this group will be not known by the world. Unfortunately that is happening to the Indians. There is a phrase in malay  saying that ' bersatu kita teguh, bercerai kita roboh'. No matter in what language it is said but we all know that, it is true and fact. The only thing which is blocking us to be united is the ego. A baseless ego.
Sri Ramana Maharishi used to tell that we must stop even use the word 'Naan' (me), because that is ego. Once there was an American philosopher who came to India and he heard about Sri Ramana Maharishi and he was so eager to meet him to have a debate. When he reached his asharam he couldn't meet Sri Ramana Maharishi as he was so busy and the American asked to come back tomorrow. Even on the next day he was not able to meet him and asked to come the following day. The third day he came aggressively and managed to meet Sri Ramana Maharishi. Once he entered the room, Sri Ramana Maharishi asked 'who are you'? He answered his name. And Sri Ramana Maharishi said, that is your name, now who are you? And he answered he is a philosopher and he asked again 'who are you' because he said that is his job. Then he answered he is from America and the saint said that is the place you came from, now who are you? He got confused and pinched himself and said this is me, me. And Sri Ramana Maharishi said, that is your body and who are you? He gave up at last and Sri Maharishi said its the ego when  you brag of yourself, and the word 'Me' it self is a ego. We don't own anything here, we came with empty and will leave empty. We don't even know what will happen on the next moment.
Well it is so foolish when we categorize among ourself and be divided. And all of our skills, speciality, will be not known of the world and will be waste. So preach to our younger brothers and sisters..... 'JATHIGAL ILLAIYADI PAPA, KULAM TALTHI UYARTHI PESUVATHU PAVAM !!!'
