SB 3.25.14

tam imaṁ te pravakṣyāmi
 yam avocaṁ purānaghe
ṛṣīṇāṁ śrotu-kāmānāṁ
 yogaṁ sarvāṅga-naipuṇam
tam imam — that very; te — to you; pravakṣyāmi — I shall explain; yam — which; avocam — I explained; purā — formerly; anaghe — O pious mother; ṛṣīṇām — to the sages; śrotu-kāmānām — eager to hear; yogam — yoga system; sarva-aṅga — in all respects; naipuṇam — serviceable and practical.
O most pious mother, I shall now explain unto you the ancient yoga system, which I explained formerly to the great sages. It is serviceable and practical in every way.

The Lord does not manufacture a new system of yoga. Sometimes it is claimed that someone has become an incarnation of God and is expounding a new theological aspect of the Absolute Truth. But here we find that although Kapila Muni is the Lord Himself and is capable of manufacturing a new doctrine for His mother, He nevertheless says, “I shall just explain the ancient system which I once explained to the great sages because they were also anxious to hear about it.” When we have a superexcellent process already present in Vedic scriptures, there is no need to concoct a new system, to mislead the innocent public. At present it has become a fashion to reject the standard system and present something bogus in the name of a newly invented process of yoga.
