Doubts about Karma and/or Rebirth I have been a staunch follower of the Buddha's words for the past 1.5 years. I do believe in the Buddha in so far as the Denial of God, Creationism, Destiny is concerned but considering the events in my life and what I see around, I am now absolutely sure that there is no Karma nor Rebirth.

In my own life experience, I was married about an year back, arranged by my family according to the traditions. Obviously I did not know the Girl before marriage nor had any sexual relations with her. It so followed that after marriage following a few days of sex with me she went ahead and had sex with her boyfriend (her friend close to her before marriage).

What followed was - She obviously found him to be more suitable for her sexual desires and immediately after that she started mentally irritating me and abuse followed. She did other stuff (like creating fissures in family) and ultimately left me after a few months. Now she is extremely happy and posting happy messages and photos in social networking and abusing me happily. The marriage laws in my country are pro female and I cannot do absolutely anything.

But the fact of the matter is that she is extremely happy (both sexually and otherwise) while I feel cheated and wronged.

Further I do see in my country in India due to a hierarchical Caste system, extremely poor people made to clean others toilets etc and pick trash due to their birth. I just spoke to an old man (about 65 years old) who told me (while crying) that he has been doing this job (cleaning toilets and picking trash) for 45 years and he is not allowed to do any other work except this and there is nobody to help him because the traditions in the country are like that.

I would like to ask you for those who believe in Karma: Where is Karma acting?
The failure of your marriage could be due to a past bad Kamma you have done. But it is also a result of you giving the chance for that past bad kamma to come into fruition. There are 4 factors affecting the results of past Kamma. Payoga Sampatti is one of them. It means skillfulness, diligence and intelligence. You can use this to avoid the results of certain past bad Kamma. 
You probably could have avoided such a heartbreak had you at least got to know her as a friend for about an year and studied her character. Even in proposals, you can do that, after both families agree. You didn't have to marry her immediately. 

You should stop focusing on the girl who left and use your Payoga Sampatti to do a better job in the future when selecting partners. Focusing on her will likely create hatred in your mind and make your situation worse. If she has done wrong, she will suffer for it in the future. But your situation will not improve whether she suffers or not. She could be enjoying life now because of her past good Kamma, her own Payoga Sampatti and Upadi(good looks) Sampatti.

In case of the old man, one is born into a low caste because of the following reasons:


  There is the case where a woman or man is obstinate &amp; arrogant. He/she
  does not pay homage to those who deserve homage, rise up for those for
  whom one should rise up, give a seat to those to whom one should give
  a seat, make way for those for whom one should make way, worship those
  who should be worshipped, respect those who should be respected,
  revere those who should be revered, or honor those who should be
  honored. Through having adopted &amp; carried out such actions, on the
  break-up of the body, after death, he/she reappears in the plane of
  deprivation... If instead he/she comes to the human state, then he/she
  is low-born wherever reborn. This is the way leading to a low birth:
  to be obstinate &amp; arrogant, not to pay homage to those who deserve
  homage, nor rise up for... nor give a seat to... nor make way for...
  nor worship... nor respect... nor revere... nor honor those who should
  be honored. -Cula Kammavibhanga Sutta
