This study explored the concept of mindfulness meditation and determined the psychological mechanisms underlying the concept. Accordingly, a case study was conducted on a brief mindfulness meditation training course involving 22 master’s students. An action research approach was used for the study. Data were collected through class discussions, student feedback, and students’ records tracked during 30 days of mindfulness self-practice. Qualitative data were analyzed through thematic analysis. During the class discussions, three major elements crucial for the practice of mindfulness meditation were elucidated and are outlined as follows: (1) use of the physical senses as the focus of attention; (2) direct experience or awareness of present-oriented being; and (3) cultivation of the consciousness of self-care and compassion through the meditation process. Moreover, students’ feedback regarding their learning experience was as follows: (1) discussing the connotations of inaction and executing meditation before training can increase individuals’ commitment; (2) meditation can help individuals clearly perceive changes in their thoughts, emotions, and physical sensations; (3) invitation, questioning, and guidance through positive discourse can enhance individuals’ autonomy and concentration; (4) awareness of the physical and mental states can help individuals shift their mentality from a doing state to a being state; (5) focusing on the awareness of present consciousness can help individuals discover new insights about themselves; and (6) concentration on breathing can promote a state of mindfulness. Observing the students’ records compiled during the 30-day self-practice revealed the following outcomes: (1) the students developed operational methods for self-help and helping others; (2) they developed enhanced self-acceptance and self-compassion; and (3) they became more introspective, establishing greater trust in their inner states. Finally, this study presents practical implications for teaching and proposes suggestions for future research.
