What do Buddhists believe about sanctity of life?
In this regard, what do Buddhists believe about contraception?
Buddhists believe that life begins (or more technically: a consciousness arises) when the egg is fertilised. That is why some birth control methods, such as the IUD, which act by killing the fertilised egg and preventing implantation are unacceptable since they harm the consciousness which has already become embodied.
Likewise, what does Buddhism think about euthanasia?
Buddhists who believe that euthanasia is a compassionate act are likely to support only voluntary, passive euthanasia as anything else does not qualify as a 'good death' and could incur negative karmic repercussions for the dying person and also the person who administered it.
To do this, place your hands together in a prayer-like gesture and give a slight bow when greeting a monk. To show more respect, you can hold your hands higher than usual, like near your forehead.
