Essentially, mindfulness helps teachers approach all their interactions with more gratitude and understanding -- positive attitudes that definitely rub off on the students.
It's not just positive thinking, though. Srinivasan demonstrates techniques from her own experience of an educator, where practicing mindfulness helps the student become more focused and stronger and their performance improved significantly.
Srinivasan attributes this to her students learning that they have a choice at every thing they do. She had her own reflections on her life, focusing on her own self-happiness, self-regulation, and responsiveness, which stopped negative thoughts or feelings of frustration from influencing her attitudes towards the children.
