"A person must always extricate himself from the private interests which fill his entire being, such that all of his ideas are centered on his own fate. This brings a person down to the depths of being small, and there is no end to the physical and spiritual suffering that comes about as a result. Rather, his thoughts, desires, his will, and the foundation of his ideas must always take into account the general – the world, mankind, Yisrael as a whole, and the entire universe. And this will also establish his personal status in the proper way."
[Oros Hakodesh volume 3, page 147].
