"Power is a double-edged sword. Do not chop off your own nose with this sword. It has happened so in Uttarakhand," Sena said.
"We are sad that this has given a revival tonic to Congress," it added.
"BJP has been embarrassed completely. Circumstances in Uttarakhand were not conducive for Congress but they have now turned beneficial for the party due to the grave mistakes of our own," it said.
