We cannot be a compassionate person just by saying words
In the teachings of Buddha and great masters they say we have to remember what kind of action we cannot have, and what kind of action we should have. So, to be mindful always is the first thing to be compassionate to others. To take care of one’s conduct of body, speech and mind is the first condition to be a good, a compassionate Dharma practitioner.
It’s not easy to be a compassionate person, because the kind of compassion described in Buddha’s teaching is of a very high level. Somehow everyone can be kind to a few, to certain people, but [real] compassion means to be kind to all sentient beings. That kind of compassion is described by Buddha in the Mahayana teachings. To establish that, we must put a lot of efforts, actions and interest into it. Also we have to try to work very hard. It is not just something that arises in your mind by wishing, but by putting a lot of efforts like Buddha himself who worked very hard to establish such genuine compassion.
Therefore, whoever really wants to do this must understand the necessary conditions to develop this mind and then try to do so. We cannot be a compassionate person by just words, but we have to be compassionate in reality. Therefore, we have to try very hard. Also, we have to be patient to really establish this kind compassion in mind. This is not easy. It is something that takes a lot of time. It took Buddha many aeons to develop bodhicitta.
