Prīti sakhya vatsalya प्रीति सख्य वत्सल्य

as from Bhakti rasāmṛta sindhu भक्ति रसामृत सिन्धु:

atha bheda-trayī hṛdyā rateḥ prīty-ādir īryate |
gāḍhānukūlatotpannā mamatvena sadāśritā ||2.5.22||

kṛṣṇa-bhakteṣv anugrāhya-sakhi-pūjyeṣv anukramāt |
tri-vidheṣu trayī prītiḥ sakhyaṁ vatsalatety asau ||2.5.23||

atra netrādi-phullatva-jṛmbhaṇodghūrṇanādayaḥ |
kevalā saṅkulā ceti dvi-vidheyaṁ rati-trayī ||2.5.24||

"The three types of rati-prīti, sakhya and vatsalya-are pleasing to the heart. They arise from deep friendliness to the Lord and are always endowed with possessiveness toward the Lord."

"When rati is found in three types of devotees-
recipients of mercy, friends and elders-it becomes prīti-rati, sakhya-rati and vatsalya-rati, respectively."

"In these three types of rati there is opening of the eyes, stretching the limbs and unsteadiness. These three types have two varieties: kevala and saṅkula."

Prīti-rati:
"When persons identify themselves as inferior to the Lord they are called the recipients of mercy (anugrāhyā). Their rati, in which Kṛṣṇa is perceived as worth of worship, is called prīti-rati."

"This prīti-rati produces attachment for the object of worship, and destroys affection for other objects."

An example from the Mukunda-māla [8]:
"O destroyer of the asura Naraka! Wherever I live according to Your desire-in heaven, on earth or in hell- I will remember Your two feet, whose beauty defeats the lotuses blooming in the autumn season, even at the time of death."

Sakhya-rati:
"Those who identify themselves as equal to Mukunda are called sakhas or friends. Their rati, with familiarity arising from a sense of equality, is called sakhya-rati. In this rati there is loud laughing, joking and no sense of reserve."

An example:
"Today, when I went to see the flowering forests of Vṛndāvan, My friends were suffering by even a moment's separation from Me. From far off, they said, 'I will be touched by Him first! I will be touched by Him first!' With hairs standing on end, they played in this way."

Another example:
"Śrīdāma said, 'Your pride has become impoverished enough in being defeated by the strength of my earms. Having boasted, say goodbye to the queen called shame [and defeat me].' 

"Vatsala-rati:
"Those persons whose rati identifies them as superiors to the Lord are known as pūjya, worthy of respect or elders. Their rati, which gives mercy to Kṛṣṇa, is called vātsalya or vatsala. In this rati, there is protecting Kṛṣṇa, blessing Him, kissing Him and touching Him."

An example:
"The forest is filled with inimical Kaṁsa's servants, who are more solid than mountains. My tender boy goes constantly to that dense forest. Oh! What should I do?"

Another example:
"Yaśodā, whose heart was soft with affection and whose breasts flowed with milk, caressed her son Kṛṣṇa while holding His chin in her fingers."

tatra kevalā -
raty-antarasya gandhena varjitā kevalā bhavet |
vrajānuge rasālādau śrīdāmādau vayasyake |
gurau ca vrajanāthādau krameṇaiva sphuraty asau ||2.5.25||
tatra saṅkulā -
eṣāṁ dvayos trayāṇāṁ vā sannipātas tu saṅkulā |
udbhavādau ca bhīmādau mathurādau krameṇa sā |
yasyādhikyaṁ bhaved yatra sa tena vyapadiśyate ||2.5.26||

Kevala-rati:
"When rati has no trace of other kinds of rati it is called kevala- (pure) rati. In Vraja, it is found in Kṛṣṇa's servants such as Rāsala, in friends such as Śrīdāma and elders such as Nanada."

Sakula-rati:
"When two or three of the three types of rati are found together in a person, it is called sakula-rati (mixed rati).It is found in Uddhava, Bhīma and Mukharā. A person is identified by the rati which is most prominent."
