In this series of four shlokas, Shri Krishna prescribed four paths or yogas to attaining Ishvara, each one more easier than the previous one. This shloka describes the path of jnyaana yoga or the yoga of knowledge. Shri Krishna says that the seeker should fix both his intellect and mind in Ishvara constantly, without any interruption. When this happens, that attainment of Ishvara is guaranteed. There is no room for “sanshaya” or doubt of attaining Ishvara when one practices jnyaana yoga. But doing so is not easy.
 
As a new year approaches, many of us start making new year resolutions such as losing weight, giving up a bad habit, cleaning the house and so on. It is our buddhi or intellect that sets firm long-term goals, targets and resolutions. Ultimately all types of plans and resolutions stem from our desires to achieve something in this world. Now, Jnyaana yoga requires us to have just one resolution and nothing else: to merge with Ishvara. But as we have seen in the second chapter, our stock of desires influences our intellect to make innumerable resolutions. This multitude of resolutions makes jnyaana yoga difficult.
 
Furthermore, our condition is such that it is not just the intellect that has many resolutions. The mana, our faculty of mind, is fickle to begin with due to the distractions of the senses. Jnyaana yoga requires the fixing of both the intellect and the mind onto Ishvara. It is in rare instances that we can achieve intellectual and mental harmony, such as studying for an exam, where we know that the stakes are high. But even that happens for a few minutes or a few hours at most.
 
So clearly, jnyaaya yoga, the foremost type of yoga, is difficult for most of us, atleast at our current stage of spiritual evolution. Is there something easier? Shri Krishna answers next.
