B.G 12.02
The Auspicious Lord said:
Those who, having fixed their mind on Me, worship Me ever steadfast and endowed with supreme faith — they are considered by Me the most devoted and accomplished.
Gīta Tātparya 12.02
The devotee should always meditate upon Śrī as supreme, and Her lord as the Supreme Person. Pleased by that, she may grant flawless worship of lord Viṣṇu. Those who worship Śrī separately suffer more, as she will not be pleased with it. The word 'yuktatamāḥ' in the context implies the most accomplished aspirants.
"This Śrī, even when worshipped, curses those who are ignorant of Viṣṇu, not His devotees, and devoid of His worship — thus says one who knows the truth of Hari.
His devotee should always meditate upon Śrī only after worshipping Him. If pleased by that, she may grant a flawless worship of Viṣṇu.
Then, by seeing Him, he attains liberation — there is no doubt. Still, she (Śrī) is supreme above all and devoid of every defect.
Those who have known Śrī as supreme, and Her lord as the Supreme Person, and worship constantly with understanding — they are indeed considered most properly devoted.
Because those who worship Śrī separately suffer more; meditated together with Viṣṇu, she indeed attains supreme satisfaction.
Otherwise, one must contemplate Viṣṇu as the consort of Śrī without flaw; only then may liberation occur, though delayed. Therefore, those who worship Viṣṇu attain liberation quickly and without suffering."
- stated thus in Parama-śruti.
The word 'yuktatamāḥ' in the context implies the most accomplished aspirants.
