]First you should try for the fruits of awareness, love, joy, peace, forbearance, kindness, goodness, faithfulness, gentleness, and self-control. The siddhis are gifts that show up when you need them. The desire for the powers they demonstrate is the sure way of never seeing them.
I completely agree with your first points but I only wish it were true that desire can't lead to powers. I wouldn't claim to any deep accomplishment but I do have concentration skills which I worked assiduously at developing. That is the basis for the development of siddhis. The siddhis and their pursuit can lead to increased suffering and become major distraction if not a complete derailment from the path to liberation.  This I can say with some certainty. In the worst case, they devolve into a morass of black magic/or and delusion. It's not for no reason that the Zen patriarches referred to all this as makyo and suggested that you ignore them. It's also not for no reason that the Lama's warn that the tantric path which goes in a similar direction is fast but dangerous.

If you do begin to develop siddhis and many practitioners do, then my *strong* recommendation is that you re-double your work to develop and practice metta regularly and the supreme siddhi which is the eye that sees enlightenment and the truth of existence directly. Yes, not grasping is a requirement for certain developments but that can be worked at and around as well without abandoning desire and becoming an arhant or even a sotapanna.

If I knew that I had the dharma eye and the siddhi of knowledge of past lives instead of being likely misguided and deluded, I'd tell you that I spent many lives chasing siddhis instead of enlightenment to my great sorrow. I don't. So, I'll just say my experience in this life tells me that's the wrong direction and you can hurt yourself and others by pointing that way. I have at times although I hope not disastrously so. Instead, head towards the light. Help your friends head in the same direction. Hang out with people who are like minded.

The Yoga Sutras are post Buddhist Hindu teaching about liberation written supposedly by Patanjali in Sanskrit. Patanjali is revered as the founder of yoga although his sutras have very little to do with hatha yoga or physical exercises. Here is one translation.

If you take a look you'll see that The Yoga Sutras are very terse. They're usually accompanied by a commentary expanding on the base text.  Here's one such which I found useful.

There's a lot of value in the Yoga Sutras but I would be remiss if I didn't point out that they are not Buddhist and their presentation of siddhis isn't a Buddist one. See here

and here for one of the Pali suttas on iddhis in the Theravadan tradition.
