Krishna rasik: the sweetness of His flute and form

veṇu-mādhuryam, yathā tatraiva (10.33.15) -

veṇu-mādhuryam: the sweetness of Kṛṣṇa's flute

yathā vā vidagdha-mādhave (1.26) -
rundhann ambu-bhṛtaś camatkṛti-paraṁ kurvan muhus tumburuṁ
dhyānād antarayan sanandana-mukhān vismerayan vedhasam |
autsukyāvalibhir baliṁ caṭulayan bhogīndram āghūrṇayan
bhindann aṇḍa-kaṭāha-bhittim abhito babhrāma vaṁśī-dhvaniḥ ||2.1.214||

An example, from Vidagdha-mādhava:
"The sound of Kṛṣṇa's flute wandered everywhere, piercing though the shell of the universe. It stopped the clouds, amazed the Gandharva Tumburu, broke the meditation of the yogīs headed by Sananda, astonished Brahmā, made Bali unsteady with longing and made Ananta dizzy."

rūpa-mādhuryaṁ, yathā tṛtīye (3.2.12) -
yan martya-līlaupayikaṁ sva-yogamāyā-
balaṁ darśayatā gṛhītam |
vismāpanaṁ svasya ca saubhagarddheḥ
paraṁ padaṁ bhūṣaṇa-bhūṣaṇāṅgam ||2.1.215||

(64) rūpa-mādhuryaṁ: the sweetness of His form.
An example, from the Tenth Canto of Śrīmad-Bhāgavatam [10.29.40]:
"Dear Kṛṣṇa, what woman in all the three worlds wouldn't deviate from
religious behavior when bewildered by the sweet, drawn-out melody of Your
flute? Your beauty makes all three worlds auspicious. Indeed, even the cows,
birds, trees and deer manifest the ecstatic symptom of bodily hair standing on end when they see Your beautiful form."

yathā vā, lalita-mādhave (8.34) -
aparikalita-pūrvaḥ kaś camatkāra-kārī
sphurati mama garīyān eṣa mādhurya-pūraḥ |
ayam aham api hanta prekṣya yaṁ lubdha-cetāḥ
sarabhasam upabhoktuṁ kāmaye rādhikeva ||2.1.217||

Another example, from Lalita-mādhava (Krishna seeing His own beauty):
"What is this great abundance of unprecedented astonishing sweetness that
has appeared? Gazing upon it, I become greedy to possess it. I desire to enjoy it with zeal like Rādhā."
