What it means
Laughter as a practice
The Sanskrit word hāsya (हास्य) means laughter, mirth. In classical Indian aesthetics hāsya is one of the nine rasas, the basic moods a work of art can awaken in us. Laughter yoga turns that mood into a practice: the laughing is done deliberately and without an occasion, the way you take up an asana or guide the breath.
The approach rests on two observations. First, the body needs no joke in order to laugh; laughing can simply be carried out like any other movement. Second, the expression works back on the mood: whoever smiles and laughs does feel lighter after a short while. Psychology calls this facial feedback. In a group, with eye contact and childlike playfulness, the pretended laughter usually tips into real laughter by itself.
What makes the laughter yoga is the breath. Between the laughter practices you breathe deeply, stretch and clap. Laughing itself is a strong, pushing out-breath, related to kapalabhati from pranayama; afterwards the in-breath flows in more deeply of its own accord. And with the lion (simhāsana) Hatha Yoga even has a laughing asana of its own.
