Before I can finally finish my CS (which took almost half a year

(From the initiation part of morphing)Morphing is mostly a practical discipline learned through experience on the field. There is relatively little theory and a lot of practice and trial-and-error involved. Much like Voiding, there is no real initiation ritual required to start practicing it, just weeks of constant meditation and focus. Aspiring Morphers fast, meditate and empty their minds until they completely separate their minds from their physical forms, at which point Morphing first becomes possible.
Now my questions
1) As long as one achieves a complete separation from the mind and body does the process matter? (example meditation)
2) Can morphing be triggered by intense emotion/s alone
2.5) If yes how volatile can it be? Let me rephrase that how unpredictable and messed up could it possibly get? will he subconsiouslly morph claws when hes angry or just be more susceptible to morph?
3) Just clarifying but can one morph into plants like have tree bark skin or have leafy hair?
4) If one does a full body morph what happens to the users clothes?
