Hello, no kundalini cannot harm consciousness, kundalini is consciousness.
Kundalini awakening can help align all of our ‘bodies’ - astral, causal, physical, emotional and so on, into one functional unit where we start functioning as an integrated individual in a multi dimensional reality.
Regardless of what any shaman said, your soul cannot be shattered. Kundalini is your soul awakening within form, giving birth to greater creations of god that you are.
The more you open up to the energy and allow it to do what it needs to do, the easier things will be, even though they can get temporarily overwhelming.
If you choose to fight with the kundalini process, you may set yourself up for unnecessary pain.
