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.
