svarupa shaktyananda | स्वरूप शक्त्यानंद
The Supreme Lord has two aspects: Impersonal form and personal form.
The sweetness of His Personal form is called svarupa shaktyananda (Devanagari: स्वरूप शक्त्यानंद ISO15919: svarūpa śaktyānaṁda). This is the special sweetness that Shri Krishna enjoys through His devotees.
Shri Krishna is both honey and honey bee. Shri Krishna's Haladini shakti enables Him to enjoys His own sweetness. That is called svarupananda.
Sweeter than svarupananda is when a devotee selflessly loves God, svarupa shakti manifests in his heart resulting in a special bliss of love that is enjoyed by God Himself.
svarupa shaktyananda is of two kinds: aishvaryananda - the feeling of reverence obscures the sweetness of love, and manasananda - the devotee completely forgets about the greatness of God, totally lost in love. This is the sweetest form of divine love bliss.
