Caitanya-caritāmṛta 6.302
jala-tulasīra sevāya tāṅra yata sukhodaya ṣoḍaśopacāra-pūjāya tata sukha naya
[jala-tulaseera sevaaya taanra yata sukhodaya shodashopachaara-poojaaya tata sukha naya]
Blended reading (Sanskrit + English inline)
jala-tulasīra sevāya tāṅra yata sukhodaya ṣoḍaśopacāra-pūjāya tata sukha naya
The amount of transcendental bliss that Raghunātha dāsa enjoyed simply by offering water and tulasī is impossible to achieve even if one worships the Deity with sixteen kinds of paraphernalia.
