"Amit Shah told me that tomorrow is the oath-taking ceremony. But, I had only two robes. If I had said no, then it would mean that I am looking for an escape route. I then went to Lucknow to attend the meeting of the BJP legislature party," Mr Adityanath said.
He was addressing a gathering on the inaugural day of the three-day UP Yoga Mahotsava in Lucknow today.
Mr Adityanath, a five-time MP and head priest of Gorakhnath Mutt, said he was a "fakir" (hermit) who lived on alms, but the people of the state had given him the whole state.
Referring to demonetisation, the Chief Minister said his government will not hesitate to take any major decision for the benefit of the people of the state.
"If needed, we will not hesitate in taking any big decision for the benefit of the 22 crore people of the state," the UP Chief Minister said, and hailed Prime Minister Narendra Modi's "bold" decision to ban high denomination currency notes.
