He also had an advise for Paswan, who he referred to as his elder brother - "get married as soon as possible."
Tejashwi Yadav's remarks were interjected by Rahul Gandhi on a lighter note: "It is applicable for me as well."
Chirag Paswan has often described himself as PM Modi's "Hanuman," affirming his loyalty to the top BJP leader.
During the 2020 Bihar polls, the LJP President had said that he does not need to use Prime Minister Narendra Modi's photos for the election campaign as PM Modi "lives in my heart; I am his Hanuman".
"If needed, I will tear open my chest and show it," Chirag Paswan, who was contesting solo against the NDA over differences with Bihar CM Nitish Kumar, had told news agency ANI.
Rahul Gandhi, Tejashwi Yadav Lead 'Voter Adhikar Yatra' in Bihar
Rahul Gandhi and RJD's Tejashwi Yadav are leading the 'Voter Adhikar Yatra' in Bihar.
The 1,300-km yatra, launched on August 17 from Sasaram, will cover more than 20 districts over a period of 16 days, and conclude with a rally in Patna on September 1.
On Saturday, Gandhi, addressing a rally in Katihar district, had deplored "attempts to steal votes" in Bihar ahead of the assembly polls, in favour of the BJP, which has "shut the doors of opportunities" for the poor since coming to power at the Centre.
"The BJP and the RSS believe that Dalits must not be emancipated, the extremely backward classes must not be allowed to move up the social ladder and women should not be given more freedom; and so they are hell bent upon destroying the Constitution," Gandhi had alleged.
