What makes the material ("mothery", LOL) world look real for others than enlightened individuals (kRtaarthaaH)? According to Patañjali it seems to be dhaaraNatvam*. This word seems to be abstract noun derived from dhaaraNaa, which in YS is the word for the sixth an.ga of yoga.
In the 3rd book, vibhuutipaada, dhaaraNaa is the first "step" of the siddhis technique: desha-bandhash cittasya dhaaraNaa. (~daysha-bandhash chittasya dhaaranaa). So, are the siddhis just very predictable and precise methods to cause a certain kind of collapse of the wave function?? * ...anaSTaM tad anya-saa-dhaaraNatvaat ("common dhaaraNaa-ness"; ablative singular from saa-dhaaraNatvam?).
