No, it is not weakly attested, there is plenty to draw from. If anything the difference is how this aspect is weakly emphasized to the masses in the West compared with what Buddhism emphasizes to laymen (but then again the end result is the same and average lay Thai Buddhist follower to put an example is not actively striving to transcend his self either)

Look at what the Desert Fathers wrote about, or Meister Eckhart or John of the Cross.

>The Three Holy Hierarchs all emphasized the importance of negative theology to an orthodox understanding of God. Later John of Damascus employed it when he wrote that positive statements about God reveal "not the nature, but the things around the nature." In addition, Maximus the Confessor maintained that the combination of apophatic theology and hesychasm—the practice of keeping stillness—made theosis or union with God possible. All in all, apophatic statements are crucial to much theology in Orthodox Christianity; the opposite tends to be true in Western Christianity, though there are a few exceptions to this rule.

The problem with Sam Harris is that he keeps picturing the Christian God as a vindictive sky-daddy, strawman under which it is difficult to see the possibility of any self-transcendence.
