Many of us may have a different opinions regarding the practice of Ngondro, and some may advice others to hectice later or just learn dharma . However, according to the many well accomplished Gurus, Ngondro is the most important part of the practice in Vajrayana tradition. Such practices will asset us to build up a confidence in pursuing our goals. Moreover, gives us sense of urgency of why we need to practice now than later. Also why it is important to practice and not just listen . Or else there is a danger of losing faith and respect to our belief. I personally feel that if we want our practice to develop a strong foundation then Ngondro is very important of part the requirement.
