The person who takes the relic can think it is Heruka’s holy mind dharmakaya, and their own mind becomes oneness with Heruka’s holy mind. They should think that strongly and keep the mind in that as much as possible.

If it is difficult to think of Heruka, then think the relic is the guru-buddha’s holy mind dharmakaya, the same.

Think all one's defilements and negative karma are purified.

One’s own mind becomes oneness with the guru-buddha’s holy mind, totally. Totally stay in that and remember it again and again.
