Professionals who are involved in mental health care during and after a disaster should be open to the diverse realities and subjects that unfold before them. It is also important for them to observe how they are responding and cultivating the capacity to do so. In order to continue working under physically and psychologically challenging circumstances without burning out, it is important to prioritize their needs, such as getting the rest they need, and establishing a teamwork system instead of putting everything on their own shoulders. At the same time, it is important to train themselves to identify what the survivor’s needs are, how to provide them and where to refer them, when necessary. Therefore, when they notice strong ideas and thoughts in themselves, it might be helpful for them to be aware of their own energy, and to distance themselves from it while accepting it. They may develop their own way of restoring their own calm and open stance. It might also be a good idea to explore ways to relax themselves by paying attention to their own breathing and the weight placed on their soles, by practicing brief stretching, or monitoring their own physical balance while walking. They might be able to refresh themselves in a short time. In order to best utilize altruism and compassion in order to be of service to others, they must first take care of and prepare themselves. It is important to be empathetic yet aware of their own and others’ differences, to stay calm while keeping their sense of being in the here and now, despite waves of uncertainty. It is also important to maintain the honesty and humility of a beginner while they hone their expert knowledge and skills. It is also important to stay humble enough to realize that they cannot be perfect while striving to be better. This is how to cultivate professional vessel as a human being. And within that vessel, various encounters will lead them to mutual growth.
