Prasada is the The grace of blessings from guru-linga-jangama.
Prasada, generally, means favor of grace of a superior being. In religion Prasad means favor or grace of God shown to the devotee. Prasad in Lingayathism signifies more than this.
To obtain favour of the Lord, the devotee has to keep constantly in mind that all that he does, eats, sees, hears, and enjoys is owing to the Lord. He expresses his gratitude to the Lord that whatever he enjoys and whatever he does is his Prasada. Hence the real Prasad is the stable cleanliness and calmness of mind; the purity and equanimity of mind, which as the soul’s agent and organ, brings about the purity and freedom of the soul. Such is the real sense and significance of Prasada
