Once we have completed a Heruka close retreat of actions and a fire puja, we are qualified to practise this self-initiation practice. This renews and strengthens our Bodhisattva and Tantric vows, purifies negativities, including Tantric downfalls, and maintains the blessings of the four empowerments of the body mandala that we received from our Spiritual Guide during the Heruka empowerment. 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 Heruka.
