Yes its worth the risk xD
Blake sits down and closes her eyes again to be able to fully concentrate on her own being and the nature with all it's energy streaming around her. Blake focuses to make sure she doesn't start breathing heavily and concentrates so she will find her balance and complete stillness again in her zen state. After a few minutes she is back in the state she was before, completely still and in an utmost balance, nothing that can get her out of it now, unless herself. She concentrates fully on the nature around her again.
After she is completely able to feel everything around her again, every single living creature and every bit of energy that is in her living surroundings, she starts making preparations for the hardest part of training so far. The stream of energy she can feel is overwhelming. The power seems to radiate from the nature itself, with a power that normally would send a shiver down her spine.
After a while, Blake is accustomed again to the power and force of the nature and not slightly overwhelmed anymore of the immense amount of power that it actually consists. She tries to do exactly the same as she would with the ninjutsu she thought of before. Drawing in the power of your opponent and absorbing it, so you can use it as your own later. This is what she needs to do with the nature's energy as well. She begins to concentrate on her own chakra first, feeling a certain kind of flow which she can control. She matches it to the flow she can control to see the difference and how to affect it. Then she starts concentrating on the flow that is not her, the immense power of the nature. She starts to manipulate her own chakra to try to draw in the nature chakra, slowly and steadily trying to 'pull' the flow of the nature towards her. Nature has enough power to lose a bit of it to me. Slowly, bit by bit, she tries to pull the energy closer towards herself, absorbing it. As she finally starts to get the hang of it after a few hours of trying to absorb the energy, she starts to feel an immense power in her body that makes her own chakra feel far more little. It starts to become a little too heavy and she suddenly remembers she needs to balance her powers as well the nature energy, her spiritual and physical powers need to be in an 1:1:1 ratio. She divides her concentration in three, focusing her spiritual and physical powers more, spiking them slightly as she draws in less nature chakra. Now her spiritual and physical powers are too much. As she turns it around again, it is the other way around and the nature chakra takes over. She quickly reverses, remembering it might harm her if she doesn't. Concentration for a few minutes, just realizing what is happening here, then she picks it back up. Trying to divide her concentration to three equals as she starts to draw the nature energy back in, then she focuses on herown powers, spiking both physical and spiritual. Adding some more natural energy, and evening it out. After a while, she is able to even all out to a perfect balance. She needed to spike both physical and spiritual energies to a hight that met the hight of the spikes of the natural energy, balancing them all out to a peaceful harmonic mass of power.
