Gītā-mālā

(1)
rasera ādhāra yei, tāṅra cite rasa-khāni
sei cittera avaśeṣe viśeṣe
śraddhā-niṣṭhā-ruci āsakti, krame haya bhāva-vyakti
rati-nāme tāhāra nirdeśe

In the heart of one who is a receptacle of rasa, rasa is stored like a reservoir. In such a heart, a special condition gradually develops – first śraddhā (faith), then niṣṭhā (steadiness), then ruci (taste), then āsakti (attachment), culminating in bhāva. This culmination is known as rati.

viruddhāviruddha-bhāva, sarvopari sva-prabhāva
prakāśiyā laya nija-vaśe
sakalera ādi-pati, haya śobhā pāya ati
sthāyī-bhāva nāma pāya rase

That bhāva which contains both contradictory and non-contradictory states, possessing its own supreme independent power, manifests itself and brings everything under its control. Becoming the original master of all, it attains great splendour. In rasa it receives the name sthāyī-bhāva.

(3)
mukhya-gauna-bhede, tāra paricaya dvi-prakāra
mukhya pañca gauṇa sapta-vidha
śānta dāsya sakhya āra, vātsalya madhura sāra
ei pañca rati mukhyābhidha

In its classification, sthāyī-bhāva is of two types – primary and secondary. There are five primary rasas and seven secondary rasas. The five principal rasas are śānta, dāsya, sakhya, vātsalya, and madhura.

(4)
hāsya adbhuta vīra āra karuṇa o raudra-kara
bhayānaka bībhatsa vibhede
rati sapta gauṇī haya saba kṛṣṇa-bhakti-maya
śobhā pāya rasera prabhede

The seven secondary rasas are hāsya, adbhuta, vīra, karuṇa, raudra, bhayānaka, and bībhatsa. All of these moods, though secondary, are fully permeated with kṛṣṇa-bhakti and enhance the beauty of rasa in its various transformations.
