All things are made of matter, energy, and consciousness. Manipulating energy and matter is useless if one does not awaken consciousness. There are many people who do exactly that, often just to impress others, acquire followers, etc. That is a waste of time. More over, the presence of energy is easy to call kundalini, yet that is just a word, and energy is just energy. So what? Sensing energy is nothing. How does that change your level of being? Feeling energy is easy. So is accumulating it. So is stealing it. So what? There is nothing impressive about energy by itself. Nor is there anything special about "powers" or siddhis. I have seen yogis do many feats, but so what? I've seen "gurus" inspire (or hypnotize) masses of people, but so what? They are not awakening anyone's consciousness. Each one has to do that themselves.
The kundalini is the energy of your divine mother. No one can force her to do anything. She only gives her gifts to those who deserve it.
What is impressive? A pure heart, a clean mind.
