In the Bhakti-rasāmṛta-sindhu (2.1.14), vibhāva is described as follows:

tatra jñeyā vibhāvās tu raty-āsvādana-hetavaḥ
te dvidhālambanā eke tathaivoddīpanāḥ pare

“The cause bringing about the tasting of love for Kṛṣṇa is called vibhāva. Vibhāva is divided into two categories — ālambana (support) and uddīpana (awakening).”

In the Agni Purāṇa it is stated:

vibhāvyate hi raty-ādir yatra yena vibhāvyate
vibhāvo nāma sa dvedhā- lambanoddīpanātmakaḥ

“That which causes love for Kṛṣṇa to appear is called vibhāva. That has two divisions — ālambana (in which love appears) and uddīpana (by which love appears).”

In the Bhakti-rasāmṛta-sindhu (2.1.16), the following is stated about ālambana:

kṛṣṇaś ca kṛṣṇa-bhaktāś ca budhair ālambanā matāḥ
raty-āder viṣayatvena tathādhāratayāpi ca

“The object of love is Kṛṣṇa, and the container of that love is the devotee of Kṛṣṇa. Learned scholars call them ālambana — the foundations.” Similarly, uddīpana is described as follows:

uddīpanās tu te proktā bhāvam uddīpayanti ye
te tu śrī-kṛṣṇa-candrasya guṇāś ceṣṭāḥ prasādhanam

“Those things which awaken ecstatic love are called uddīpana. Mainly this awakening is made possible by the qualities and activities of Kṛṣṇa, as well as by His mode of decoration and the way His hair is arranged.” (B.r.s. 2.1.301) The Bhakti-rasāmṛta-sindhu (2.1.302) also gives the following further examples of uddīpana:

smitāṅga-saurabhe vaṁśa- śṛṅga-nūpura-kambavaḥ
padāṅka-kṣetra-tulasī- bhakta-tad-vāsarādayaḥ

“Kṛṣṇa’s smile, the fragrance of His transcendental body, His flute, bugle, ankle bells and conchshell, the marks on His feet, His place of residence, His favorite plant [tulasī], His devotees, and the observance of fasts and vows connected to His devotion all awaken the symptoms of ecstatic love.”
