From time to time GS members come here in religion forum and demand the procedure of Istekhara. I found a very good lecture on it and therefore sharing it here so you guys could benefit from it. Shaykh Abdul Nasir clearly describing the process of Istekhara in deail.
You can read the transcript of the lecture here. Abdul Nasir Jangda | Istikharah: How to and Why? - MuslimMatters.org
