Lo yoga non è passivo. Dobbiamo partecipare alla vita. Per farlo bene, dobbiamo lavorare su noi stessi - T.K.V. Desikachar

Avidyā es la raíz que causa los obstáculos que nos impiden reconocer las cosas como en realidad son. Los obstáculos son: asmitā (ego), rāga (apego), dveṣa (rechazo) y abhiniveśa (miedo)

It is when obstacles do not seem to be present that it is most important to be on our guard. Nothing is more fraught with danger than to mistake a temporary state for a permanent one. We must expect cycles of clarity and confusion, recognizing that falls from clarity may be more disturbing than a state of no clarity at all. When obstacles appear, it is necessary to advance toward a state of reflection to reduce their impact and prevent them from taking over.

prāṇāyāma is first and foremost to give us many different possibilities for following the breath. When we follow the breath, the mind will be drawn into the activities of the breath. In this way prāṇāyāma prepares us for the stillness of meditation.
