Thanks! Of course men can have Shakti, but it is a feminine force (generative, creative, life-giving), and in Hindu tradition, women are considered the vessels of Shakti, so I don't spend a lot of time thinking about it in the context of men. It's not just animal magnetism and power (in a patriarchal sense of that word), which seems to be how these "gurus" are using it. They are co-opting the Feminine for their own purposes, it seems like.
"Shakti may be personified as the gentle and benevolent Uma, consort of Shiva, or Kali, the terrifying force destroying evil, or Durga, the warrior who conquers forces that threaten the stability of the universe. Goddess worshippers often view their deity as the all-powerful Supreme Being, second not even to a male god. There are enduring goddess traditions all over India, especially in West Bengal and south India. Goddesses symbolizing various aspects of power very often predominate in village culture. Village men, women, and children, when they pray for immediate needs, address a female, not a male."
