Just because something fs may be done, it is not on ethical reason for making it an actuality. Living in an interdependent world where all are related to one another we should take extra care before losing the beliefs and customs of Thai people. Buddhism remains the basis in the mounding and development of Thai cultural values. And one cannot understand or appreciate Thai culture without having some basic comprehension of Buddhist beliefs and values. The cycle of rebirth is alluded to the round of existence in which all beings revolve according to the quality of their deeds.
Good deed brings good result while bad action leads to bad result.
In other words from the Buddhist viewpoint rebirth of all beings are the natural results of their own deeds, good or bad. For they reap what they sowed in the past, and will be reborn according to the nature of their present deeds. When a being dies, the kammic result acting as the individual life-force passes to other forms of existence, endlessly exalting or degrading successive rebirths. Such cessation is referred as nibbana. It is an important means for the accumulation of merit to benefit present life and rebirths.
