Samsara and Karma
Six Realms of Existence
According to the Buddha’s teachings there are six realms or planes of existence: the four lower realms of suffering, the human realm, and the higher planes of the various heaven worlds.
The six realms are different forms of existence in which we can take rebirth. They can also be thought of as psychological states we experience in our current life in the human realm.
The lower realms are conditioned by intense anger, hatred, greed, and delusion, and when we cultivate these states, developing them as a pattern of response to situations, they become a strong force in the mind.
The six realms are different forms of existence in which we can take rebirth. They can also be thought of as psychological states we experience in our current life in the human realm. The human realm is the first of the happy planes of existence. But it doesn’t mean that there is no suffering. Human Realm is the most conducive for developing wisdom and compassion because of its particular mixture of pain and pleasure that provides the best circumstances for deep understanding and realization.
The great inspiration of the Buddha’s teaching is that we must each take ultimate responsibility for the quality of our lives. Given certain volitional actions, certain results will follow. When we understand that our lives are the unfolding of karmic law that we are the heirs to our own deeds, then there grows in us a deepening sense of responsibility for how we live, the choices we make, and the actions we undertake.

Karma
Karma is the only reason that you ,me and rest of the world is in Samsara.
Here Samsara is taken as a cycle of birth and death in to different forms of life. We all are born and someday we will die, and will be born again, and again, and again until we remove all Karmas from our soul.
Given certain volitional actions, certain results will follow. When we understand that our lives are the unfolding of karmic law that we are the heirs to our own deeds, then there grows in us a deepening sense of responsibility for how we live, the choices we make, and the actions we undertake.
