The following is an excerpt from a teaching by His Holiness Penor Rinpoche called “Meditation”
The samsaric sufferings we experience are the result of non-virtuous actions of the body, speech and mind. For example, if somebody performed a negative action, such as killing, for instance, then the result based on that action, the reaction or its ripening Karma, is for the person’s life to shorten. And in the next lifetime he may be born in the hell realms where he has to suffer the result of the Karma he created. Similarly, if someone thinks that in this lifetime they could obtain material possessions by stealing or robbing, like a rat who steals all kinds of grains, such stealing ultimately ripens its fruit so that in the next lifetime, or maybe in this lifetime, this person may actually not have enough wealth and become very poor. Even the physical body’s negative actions, such as sexual misconduct, have negative results. This can be that within one’s lifetime, or in the next lifetime, one’s family will not be in harmony and will suffer quarrels and fighting. Similarly there are four negativities of speech, which are known as lies, interferences, harsh words and gossip. From these are certain negative results that one experiences, such that whatever one tries to tell, people will not believe. Even when one tries to say something beneficial it will seem like one is trying to harm somebody. Likewise with the three negative mental actions: Greediness, thoughts of harming others and wrong views. Based on these, one will not have success whatever one tries to do in this lifetime or in future lifetimes, one will experience a lot of harm from other beings, one will be unable to remain together with one’s masters, teachers or good friends and so on. These are examples of the ripening of negative actions.
So understanding all these causes and conditions are based on the actions of our body, speech and mind, we should then try to abandon all the ten negative actions and try to train ourselves so that our mindstream flows with the spiritual path. Then one can practice and accumulate all the virtuous activities. The teachings say that if one follows the worldly aspect of the Dharma practice, with good or positive behaviors, that naturally turns into a spiritual path through which one can have peace and happiness. In this way, with our bodies, speech and mind, in whatever conditions of life, it is very important to try to benefit others and have loving kindness toward everybody.
