The very desire to seek spiritual enlightenment is in fact nothing but the grasping tendency of the ego itself, and thus the very search for enlightenment prevents it. The 'perfect practice' is therefore not to search for enlightenment but to inquire into the motive for seeking itself. You obviously seek in order to avoid the present, and yet the present alone holds the answer: to seek forever is to miss the point forever. You always already are enlightened Spirit, and therefore to seek Spirit is simply to deny Spirit.

And resting in the ocean, dipped into the sea, I find glimmers of One Taste everywhere.

Do you even recognize your own consciousness?

Saving the biosphere depends first and foremost on human beings reaching mutual understanding and unforced agreement as to common ends. And that intersubjective accord occurs only in the noosphere. Anything short of that noospheric accord will continue to destroy the biosphere.

As Hubert Benoit said, it is not the identification with the ego that is the problem, but the exclusive nature of the identification. When our self-identity expands beyond the ego, into the deeper psychic, then even into the Unborn and One Taste, the ego is simply taken up and subsumed in a grander identity. But the ego itself remains as the functional self in the gross realm, and it might even appropriately be intensified and made more powerful, simply because it is now plugged into the entire Kosmos.

Furthermore, it is not that Spirit is present but you need to be enlightened in order to see it. It is not that you are one with Spirit but just don't know it yet. Because that would also imply that there is some place Spirit is not. No, according to Dzogchen, you are always already one with Spirit, and that awareness is always already fully present, right now. You are looking directly at Spirit, with Spirit, in every act of awareness. There is nowhere Spirit is not.

Conscious means "having an awareness of one's inner and outer worlds; mentally perceptive, awake, mindful." So "conscious business" might mean, engaging in an occupation, work, or trade in a mindful, awake fashion. This implies, of course, that many people do not do so. In my experience, that is often the case. So I would definitely be in favor of conscious business; or conscious anything, for that matter.
