From Gyume Tantra Monastery:
The ingredients of the following nectar pills are each created in the retreat corresponding to the Buddha aspect and blessed for 24 hours, after which the ritual ends with a fire puja. After all 3 retreats, the pills are fully blessed and extremely powerful.
They have a strong spiritual effect against obstacles on all three levels, against spirits and demons, and one does not fall back into the three lower realms.
