Neriya levels 1 - 5 (prerequisite Drisana 3) The Neriya sequence of five levels can be started after taking Drisana level 3. What Drisana achieves by attunements, Neriya achieves autonomously. In other words, with Neriya you have less control over the rate of your spiritual change. The disadvantage of this is that your emotional 'stuff' and baggage may come up when you do not expect it, but the advantage is that spiritual work is being done on you all the time without you having to consciously direct it.. For this reason, we say that Neriya is for the true 'spiritual warrior'.
