virilification; the restoration of normal sexual functions (also refers to restoring or enhancing sexual performance and pleasure, mainly used for the male) Comment: in terms of the practice of Secret Mantra, the union of male and female is used with an entirely different consciousness. In this practice, the bliss arising from union of male and female is used to realize the emptiness of inherent existence in a totally non-dualistic and powerful way. For this practice to be effective, the regenerative fluid must be in good condition, and thus the importance of virilification is not limited to bringing physical pleasure or maintaining a family lineage but also includes enhancement of a high state of spiritual experience.
