Why would all our good deeds not be sufficient to earn us a place in Olam Haba? "Even if his good deeds were as numerous as the sand in the see they still would not be equal to even one of the favors bestowed upon him by the Creator, all the more so if he committed a sin":
pg 439.
Lilu Nishmat Rav Dovid Feinstein ז"לNefesh Hachaim
The idea that the world is actually an illusion and that nothing exists other than H'shem's Oneness is a lofty concept that should be carefully approached and distanced from at the same time. One must understand that Kabbalah and its lofty teachings are not for everyone and it may do more harm than good if the one learning it is not on the correct level or mindset to be doing so.
