Gītā-mālā

(1)
rati-āsvāda-hetu yata, vibhāva nāmete khyāta
ālambana uddīpana haya
viṣaya-āśraya-gata, ālambana dui mata
kṛṣṇa kṛṣṇa-bhakta se ubhaya

All the things which cause one to taste attachment (rati) for the Lord are known as vibhāva (special stimulants). These are of two types: ālambana (supporting causes) and uddīpana (exciting stimulants). Ālambana again has two divisions: viṣaya (the object of love, Kṛṣṇa) and āśraya (the shelter of love, the devotee of Kṛṣṇa).

nāyakera śiromaṇi, svayaṁ kṛṣṇa guṇa-maṇi
nitya-guṇa-dhāma parātpara
tāṅra bhāve anurakta, guṇāḍhya yateka bhakta
siddha eka sādhaka āra

Lord Kṛṣṇa Himself is the crest jewel of all heroes. He is the jewel mine of all transcendental qualities, the eternal abode of all virtues, and the Supreme Absolute Truth. Devotees who become attached to Him are endowed with many spiritual qualities. Some are siddha (perfected), and others are sādhaka (practitioners).

(3)
bhāva-uddīpana kare, uddīpana nāma dhare
kṛṣṇera sambandha vastu saba
smitāsya saurabha śṛṅga, vaṁśī kambu kṣetra bhṛṅga
padāṅka nūpura kala-rava

All objects that stimulate awakening of bhāva are called uddīpana. These include everything related to Kṛṣṇa: His smiling face, bodily fragrance, buffalo horn, flute, conch, His abode, the buzzing of bees in Vraja, the marks of His lotus feet, His ankle bells, and the sweet sound of His ornaments.

(4)
tulasī-bhajana cihna, bhakta-jana-darśana
ei-rūpa nānā uddīpana
bhakti-rasa-āsvādane, ei saba hetu-gaṇe
nirdeśila rūpa-sanātana

Other stimulants include worship of Tulasī Devī, devotional symbols and practices, and the darśana of the Lord’s devotees. In this way there are many causes that awaken the taste of bhakti-rasa. All these have been described by Rūpa and Sanātana.
