Two conditions must come together in order for us to realise the unborn nature of all phenomena: the inner and outer lama. When we build a proper foundation and follow an outer lama with devotion, it becomes possible to catch a glimpse of inner wisdom. This inner wisdom becomes a guide for us as well, and it is called the inner lama. In our individualistic Western culture, most people really like the idea of the inner lama! It is important to remember reliance on the outer and inner lamas together. We do not enter the path and then just follow our own intrinsic wisdom, which will likely turn out to be egoic. Without the inner and outer lama, even the practices of Dzogchen will not lead us to realisation quickly.
