After some time things begin to fall into place and take affect. One begins to understand that there actually cannot be any other way. An ascent is one’s consent with the Creator’s doing. In that state, one feels, full and eternal, separated from the body and connected only with spirituality.

“…he who says that there is another power in the world, namely shells, is in a state of “serving other gods.” It is not necessarily the thought of heresy that is the sin, but if he thinks that there is another authority and Force apart from the Creator, by that he is committing a sin.

Furthermore, he who says that man has his own authority–meaning that he says that yesterday he himself did not want to follow God’s ways, that, too, is considered to be committing the sin of heresy. It means that he does not believe that only the Creator leads the world.”
(Yehuda Leib HaLevi Ashlag (Baal HaSulam, Shamati 1, There’s None Else Besides Him)
