Bhagavad Gita · Raja Vidya Raja Guhya YogaChapter 9, Shloka 24 (9.24)

Shankaracharya. Sarveṣāṃ yajñānāṃ devatātmatvena bhoktā ca prabhuḥ eva ca, mat-svāmiko hi yajñaḥ — as the self of the deities, the enjoyer and lord of all yajnas; adhiyajño'ham evātra (8.4) — the evidence; avidhi-pūrvakam iṣṭvā yāga-phalāt cyavanti — worshipping in the wrong way, they fall from the fruit of the yajna.

Acharya Ramanuja — the wonder of intention. Prabhuḥ eva ca tatra tatra phala-pradātā ca aham eva — the giver of fruit is also me; and the wonder: aho mahad idaṃ vaicitryaṃ yad ekasmin eva karmaṇi vartamānāḥ saṃkalpa-mātra-bhedena kecid atyalpa-phala-bhāginaḥ cyavana-svabhāvāḥ ca bhavanti kecana anavadhikātiśayānanda-parama-puruṣa-prāpti-rūpa-phala-bhāginaḥ apunarāvarttinaḥ ca — ah, what a great wonder! Doing one and the same action, merely through a difference in intention, one gets a tiny fruit and falls, another attains the Supreme Person, who is boundless bliss, and does not return.
