Śrīmad-Bhāgavatam
[Canto 4, Ch. 24]
The devotees, the  jñānīs , who are known as  mokṣa-kāma , and the  karmīs , who are known as  sarva-kāma , are all aspiring to worship the Supreme Personality of Godhead, Viṣṇu. Even when one performs  yajñas , as stated here ( kriyā-kalāpaiḥ ), he should always remember that the demigods are but agents of the Supreme Lord. Actually the worshipful Lord is Viṣṇu, Yajñeśvara. Thus even when different demigods are worshiped in the Vedic and Tantric sacrifices, the actual goal of sacrifice is Lord Viṣṇu. Therefore in  Bhagavad-gītā  it is said:
ye 'py anya-devatā-bhaktā yajante śraddhayānvitāḥ te 'pi mām eva kaunteya yajanty avidhi-pūrvakam
“Whatever a man may sacrifice to other gods, O son of Kuntī, is really meant for Me alone, but is offered without true understanding.” (Bg. 9.23)
Thus the worshipers of various demigods also worship the Supreme Lord, but they do so against the regulative principles. The purpose of the regulative principles is to satisfy Lord Viṣṇu. In the  Viṣṇu Purāṇa  the very same thing is confirmed:
varṇāśramācāravatā puruṣeṇa paraḥ pumān viṣṇur ārādhyate panthā nānyat tat-toṣa-kāraṇam (Viṣṇu P. 3.8.9)
Here it is clearly mentioned that the  karmī ,  jñānī  or  yogī —in fact, everyone—worships Lord Viṣṇu if he is actually expert in knowledge of the  Vedas  and  Tantras . The word  kovidāḥ  is very significant, for it indicates the devotees of the Lord. Only the devotees know perfectly that the Supreme Personality of Godhead, Viṣṇu, is all-pervading. Within the material energy, He is represented by the five material elements as well as the mind, intelligence and ego. He is also represented by another energy, and all these manifestations in the spiritual and material world combined are but representations of the different energies of the Lord. The conclusion is that the Lord is one and that He is expanded in everything. This is understood by the Vedic version:  sarvam khalv idam brahma . One who knows this concentrates all his energy in worshiping Lord Viṣṇu.
