(3) According to the Gita, is yoga an end result or a process? Describes three methods that Krishna speaks about that will help to attain “yoga”.

I think yoga is the process and the end result of the process as well. The two can't be separated. In the context of the Bhagavad Gita, (Yoga) describes a unified outlook, serenity of mind, skill in action and the ability to stay attuned to the glory of the Self (Atman) and the Supreme Being. In order to attain clarity Krishna explains that one must gain control over lust, anger and greed.
