Why Gyan kanda (method of knowledge) is inferior to Karma Kanda (method of Yagik Karma)

Often vedantian claim only knowledge can burn (i heard I dont know exactly)the seed of desire and Yagik Karma only leads to desire fulfillment so Gyan kanda is superior or only true way to liberation. To my own surprise I find Karma Kanda superior (it sounds nothing less than Andhabiswas) -When everything is 1 even maya is part of Brahaman and this 3 out of 4 states are reality too including seeds of desire, then nothing is left to burn. -Yagik Karma unlike method of knowledge is performed at particular time with perfect notes and prescribed words and group of words, which are capable of producing effects in brain, even activate past memories. While knowledge is past, it is not present, it is invocation of memory only. It can lead to Yagik Karma at best or functioing in the same style as previous however memory is memory at best it helps to function and at worst it leads to sorrow (remembering sadness it produces effect of sadness, remembering happiness it produce sorrow by knowing why that is not in present). Etc. (just random thoughts, can be entirely wrong )
