Once we have completed a Vajrayogini close retreat of actions and a fire puja, we are qualified to perform this self-initiation practice. This renews and strengthens our Bodhisattva and Tantric vows, and purifies negativities, including Tantric downfalls. Practising self-initiation regularly is important because maintaining our vows and commitments is the foundation of all Tantric attainments and, if we break our vows and commitments and do not restore them through an appropriate method, this will be a great obstacle to our attaining Tantric realizations. Through taking self-initiation regularly we open the door to successful practice of generation stage and completion stage, we will be cared for by Heruka and Vajrayogini in all our lives and receive their blessings so that we quickly attain the Pure Land of Vajrayogini.
