On Svāminī’s order Tulasī has gone to Nandīśvara to serve Śyāmasundara Her own cooked dishes there. After Śyāmasundara has eaten, mother Yaśodā lovingly gives some of His sweet remnants to Tulasī, so that she can bring them to Svāminī. Dhaniṣṭhā had secretly mixed some of Kṛṣṇa’s adharāmṛta (lip-nectar, or food-remnants) in it. Śrī Kṛṣṇa knew what Dhaniṣṭhā wanted, so, while giving her a hint with His eyes, He spat some food out as if He did not like it. Dhaniṣṭhā picked that food up and mixed it with the sweets that Yaśodā had reserved for Śrī Rādhikā. Dhaniṣṭhā is responsible for all devotional services at Nandīśvara, as is Kundalatā. Both of them are very attached to the Loving Pair. They know what is on Their minds and they render their services in secret, unnoticed by others.

Meanwhile, in Yāvat (Rādhā’s in-laws’ abode), after sending Tulasī to Nandīśvara, Śrī Rādhikā has fainted out of powerful feelings of separation from Kṛṣṇa and the sakhīs are unable to bring Her back to Her senses. Then Tulasī comes back from Nandīśvara.

tad viśleṣa-jvara sama lave’pyakṣamā yarhyabhūvan
gāndharvāyā visa kiśalayośīra candrāmbujādyāḥ
kāpyāgatya vyadhita lalitādeśatas tarhi tasyās
tad vṛttāntāmṛta rasa pṛṣat secanaṁ karṇa-randhre
(Kṛṣṇa Bhāvanāmṛta 17,7)

“Even cool things like lotus stems, lotus pollen, uśīra (vertiver), camphor, sandal paste and lotus flowers were not able to bring down Gāndharvikā’s (Śrī Rādhikā’s) hot fever of separation from Kṛṣṇa. Just then one sakhī (Tulasī) came from Nandīśvara and began to sprinkle Her earholes with drops of the nectar-like stories about Kṛṣṇa, being ordered by Lalitā.”
Śrī Rādhikā immediately comes back to Her senses, sits down and says: “O sakhi! In My dream My desert-like ears suddenly felt a shower of nectar!”

Lalitā says: āyāteyaṁ sumukhi! tulasī mañjarī goṣṭha rājñā gehāt sakhyus tava yadavad vṛttam asmād ajāgaḥ – “O Fairfaced sakhi! It is Tulasī Mañjarī, who has come back from the abode of the Queen of Vraja! She brought You back to Your senses by sprinkling You with the nectar of Your friend Kṛṣṇa’s pastimes!”

Svāminī sees Tulasī before Her and embraces her. Svāminī has an extraordinary love for Tulasī. She knows that Tulasī has come back after serving Her wholeheartedly.
Again Tulasī serves her Svāminī in an extraordinary way by sprinkling Her ears with the nectar of Kṛṣṇa’s afternoon-pastimes.
Svāminī asks Tulasī: “What did mother (Yaśodā) say?”
Tulasī says: “Hey Śyāmājū! How can I describe mother Yaśodā’s affection as she held her forehead on mine, calling me Your maidservant?”

āmāra lalāṭe lalāṭa prīte diyā; preme matta hoiyā tomāra kuśala puchiyā
tomāra-i āmi ihā jāni vraja-rāṇī; sneha kori koto prīta korilā āpani
(Prārthanāmṛta Taraṅginī)

“Lovingly she held her forehead on my forehead and inquired about Your welfare, intoxicated by ecstatic love. How much love the Queen of Vraja gave me, knowing me to be Yours!”

Svāminī pulls Tulasī on Her lap and repeatedly asks her: “He has eaten nicely, hasn’t He? I couldn’t cook so nicely! I’m sure He didn’t like the sweets! You were close by, weren’t you?” Svāminī thoroughly questions Tulasī, and fortunate Tulasī gives sweet answers to all the questions, thus rendering a wonderful service by submerging Svāminī in the nectar-ocean of talks about Kṛṣṇa: “Dhaniṣṭhā has given me some remnants of Kṛṣṇa’s food and I brought it with me for You!”

Śrī Rādhikā is like a Cātakī-bird which does not eat anything else but the nectar from Kṛṣṇa’s lips. As soon as She hears about this nectar, the thirst of Her ears and Her heart is immediately quenched.

“Didn’t He say anything to you?”, She asks Tulasī. “How can He, in front of His superiors?” Tulasī answers. “With His eyes He asked me if He could meet You tonight in Vṛndāvana and I told Him, also with the hints from my eyes, “Surely You will meet Her!”

Svāminī says: “Tulasi! Look at Me once! I’m so unfortunate that I could not see Him personally! Let Me see if He is hidden in your eyes or not!”, and She gazes in Tulasī’s eyes without blinking. Her eyes are full of tears and Her body is shivering of ecstatic love.
“When I look into your eyes I can understand that you have seen Him! Otherwise your eyes could never have been so beautiful!”, Svāminī says.

What a wonderful service Tulasī is rendering by carrying Kṛṣṇa’s picture to Svāminī in her eyes! Blessed is this maidservant! Now Śrīmatī starts to take Her meal. How wonderful is Tulasī’s expertise in devotional service!
