We have mentioned many times before that renunciation and bodhicitta are the basis of Vajrayana practice. Why is it necessary to reiterate this point here? Because they are the prerequisite a practitioner must have; without renunciation and bodhicitta, no benefit is to be derived from undertaking even the very sacred Vajrayana tantras such as Dzogchen—the Great Perfection. Only with renunciation and bodhicitta as a foundation can one formally enter Vajrayana practice.
