Forgetfulness, which is more problematic than you think, often leads you to take wrong decisions. So, think sufficiently before any significant action and in strong emotions.
Though you feel like you are careful about your life, you actually have a lot of forgetfulness, unawareness and emotionally induced thoughtlessness that makes you do many mistakes. So, remember always that you can be taken over by bad consequences if you do not think sufficiently before every significant action.
Especially, think when you talk, when you get greatly attracted to something and when you feel angry.
For many people, a religion is also a groupism other than a spiritual path. For many people, spirituality and principles in a religion are only a self excuse to enjoy the benefits of the religious groupism. Some people try to convert followers of other religions in to the self followed religion in order to get convinced that the self followed religion is greater than other religions. Some people convert followers of other religions to reduce enemies. Some people make conversions with love towards others, in order to bring them to better (as per their understanding) path. People may not convert others when benefits of groupism and exploitation of other religious groups are more than the benefit of converting others (including the other groups in to self group may make the self group poor and there will be no way to exploit the other groups. This is similar to what we see in the groups of dogs). Some governments and political parties encourage or discourage religious conversions for political benefits.
There do not exist two principles being correct and contradictory simultaneously. So, if a religious principle is contradictory to some other religion’s principle, only one of them may be correct or none of them may be correct.
