Ra ties Pluto in the 36 to the question about life turning from yes to no. Neptune is what actually dissolves the old afterwards. Ra traces Neptune along the same experiential way that Pluto switched. It was discovered in Gate 30 in 1846 and returned there during the years he was teaching. About Neptune in the 30, the gate of the Fates, he warns that you do not see your way clear, and that it dissolves diversity. His end dates for this work differ. At one point he says the complete dissolving of the way will be achieved by 2057, when Neptune reaches the 35. At another he calls 2162 the absolute number, when Neptune has finished and the generation born under the Cross of Planning has left the plane. So Ra is not consistent on the year. What stays the same is the pairing: the change itself in 2027, the full effect only generations later.
