Śrīmad-Bhāgavatam
[Canto 3, Ch. 25]
called material happiness, material distress will follow. This is the law of the material world. Lord Kapila states that the  yoga  system is the science of the spirit. One practices  yoga  in order to attain perfection on the spiritual platform. There is no question of material happiness or distress. It is transcendental. Lord Kapila will eventually explain how it is transcendental, but the preliminary introduction is given here.
TEXT 14
तमिमं ते प्रवक्ष्यामि यमवोचं पुरानघे ।
ऋषीणां श्रोतुकामानां योगं सर्वाङ्गनैपुणम् ॥१४॥
tam imam te pravakṣyāmi yam avocam purānaghe ṛṣīṇām śrotu-kāmānām yogam sarvānga-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-anga—in all respects; naipuṇam—serviceable and practical.
TRANSLATION
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.
PURPORT
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 .
