If you read Ra carefully, you’ll realize at some point that there are not two paths out of third density. There is a third path, certainly much harder than the path of service to others, but perhaps not as demanding as the exigencies of service to self, though infinitely more rewarding than both of them.
This particular way out is alluded to in various passages speaking of reaching the gateway to intelligent infinity, which grants the seeker an automatic ticket out of third density. Clues about reaching enlightenment are strewn throughout the material, however, there is a very telling one in the following excerpt (29.29):
I am Ra. The gateway to intelligent infinity is born of, shall we say, the sympathetic vibration, in balanced state, accompanying the will to serve, the will to seek.
The crucial words here are “the will to serve, the will to seek“. While subtle, the hint, given the conciseness and precision of Ra’s language, is quite clear: from the perspective of attempts to reach enlightenment, the will to serve is equal to the will to seek.
What are we to seek, though? The Ra material provides a lot of pointers on this topic, however, for a completely independent corroboration, we can also look to the Hindu traditions for a clue. Outside of the bhakti yoga and karma yoga paths, various Hindu approaches to self-realization do not really put a lot of emphasis on serving others; it’s almost an afterthought or a side effect of the primary path. And the primary path? Whatever its particular expression — jnana, raja, tantra, or any other — the goal of every single type of yoga is reuniting with God or becoming God.
Thus, what all earnest yoga practitioners strive for, what they seek is the same in all cases: the ultimate Truth of Reality. This, then, is the answer to the question implicitly alluded to in Ra’s “the will to seek”. The desire and will to seek God, to seek the Truth of the Absolute, and to become one with that Truth is equivalent to serving others or serving the self.
To be clear, let’s stress again that they are equivalent from the perspective of reaching self-realization, not from the perspective of graduating from the third density. This distinction is important, because while the former goal necessarily contains the latter, the opposite is not the case — the vast majority of people who graduate from the third density do not reach enlightenment; they do so by serving others. That’s because from the practical perspective, achieving enlightenment is infinitely harder than achieving 51% of serving others in intention and deed, although the reward is so much greater.
So there you go — just lock yourself in a cave, pretend that humans don’t exist, and after only a couple of dozen incarnations you’ll be able to come out and proclaim some noble truths. Unless, while you were incommunicado, humanity decided to leave the third density as a whole by applying a few thoughtfully placed nukes to the planet’s surface.
