Premanand Maharaj Ji
Why is patience so important on the path of bhakti and under a guru?
Impatience is a fault in bhakti
Impatience is a fault in bhakti (loving devotion), and gurus test your patience. Keep great patience, including in your naam jap (chanting).
So become patient. Impatience is a fault in bhakti. We should keep great patience, not impatience. And gurus test your patience.
