Excerpts from Sadhguru's talks
Question: Why is meditation the quality of Dhyanalinga temple?
Sadhguru: Why we have chosen meditation for the temple, why the predominant quality, it's not that devotion is out, devotion is fine, but the predominant quality of the temple, and the work that we do is meditation not devotion. Simply because, though devotion is definitely the quickest way for one to grow, devotion can be very, very deceptive. You know it, isn't it? Today you think you're absolutely devoted, tomorrow morning one little thing goes wrong and your devotion just evaporates. That's not the nature of meditation though, you can't deceive yourself. Maybe it'll not happen to you for a long time but when it happens, it happens. There's no going back on it.
So we have chosen meditation because thinking minds and devotion don't go so much well together. If you could become simply devote, then we would have definitely pushed you into devotion because that would be a quicker way to grow. But the problem with devotion is you don't know whether you're going forward or backward. You will not know which way you're going because it's just emotion; raising emotion to such a pitch that it'll break barriers for you. But there is no check on it, there's no control on it and thinking minds can be very deceptive with devotion. Devotion may not happen, just deception may happen. So the main quality of the temple is meditation.
