The path of devotional service is very difficult, even for great kings who have conquered many enemies. Although these kings were victorious on the battlefield, they could not conquer the bodily conception. There are many big leaders, yogīs, svāmīs and so-called incarnations who are very much addicted to mental speculation and who advertise themselves as perfect personalities, but they are not ultimately successful. The path of devotional service is undoubtedly very difficult to follow, but it becomes very easy if the candidate actually wants to follow the path of the mahājana.
