On the meeting, Baba Ramdev said he had come to invite Lalu Yadav to attend International Yoga Day celebrations.
Yoga guru Baba Ramdev has got an unusual friend in RJD chief Lalu Prasad Yadav, who has been critical of him in the past due his links with the BJP or Bharatiya Janata Party and RSS or Rashtriya Swayamsevak Sangh.
"People are jealous of Baba Ramdev because he is highly successful... he has earned everything through sheer hard work," the Rashtriya Janata Dal or RJD leader said.
Unusual camaraderie was on display when the two met here, with Ramdev hugging and rubbing facial cream on Mr Yadav's forehead. Both have been critical of each other in the past over their political ideologies.
Asked whether he would endorse the yoga guru's Patanjali products, Mr Yadav said: ''I am a permanent brand ambassador of his products.''
