Tulasi Glorification – Sri Caitanya Caritamrta
Sri Caitanya Caritamrta – Ādi 3.105-106
Advaita Ācārya considered the meaning of the verse in this way: “Not finding any way to repay the debt He owes to one who offers Him a tulasī leaf and water, Lord Kṛṣṇa thinks, ‘There is no wealth in My possession that is equal to a tulasī leaf and water.’
Sri Caitanya Caritamrta – Ādi 3.107
Through devotional service one can easily please Lord Kṛṣṇa with a leaf of the tulasī plant and a little water. As the Lord says in the Bhagavad-gītā (9.26), a leaf, a flower, a fruit or some water (patraṁ puṣpaṁ phalaṁ toyam), when offered with devotion, very much pleases Him.
Sri Caitanya Caritamrta – Madhya 22.125
“Tadīya means the tulasī leaves, the devotees of Kṛṣṇa, the birthplace of Kṛṣṇa (Mathurā), and the Vedic literature Śrīmad-Bhāgavatam. Kṛṣṇa is very eager to see His devotee serve tulasī, Vaiṣṇavas, Mathurā and Bhāgavatam.
