"Buniyaad, in many ways, laid the foundation of my career," says Nath.

"On the first day of shooting, we were all very nervous. We took about nine takes and still nothing was working. Later, we came to know that this was Sippyji's way to warm up," he adds.

In the serial, Haveliram goes missing. While all others think that he is dead, his wife Lajoji refuses to believe so. The whole country was hysterical. And when he returned, we realised the power of television for the first time.

"This is one thing I'll never forget [the mass reaction to Haveliram's return]. And it helped me realise the need for honesty in the character that an actor must portray," he adds.

Nath was later seen in serials like Thoda Hai Thode Ki Zaroorat Hai, Tara, Imtihaan, and films like Maine Pyar Kiya, Qayamat Se Qayamat Tak and Hum Aapke Hain Kaun among others. He has mostly played a doting father.

In real life, he insists he is not strict with his 16-year-old daughter and 13-year-old son. "When I am not acting, I like to cook at home and spend time with my family. If I was not an actor, I would have been in the restaurant business," he says.

Nath is currently working in serials like Astitva - Ek Prem Kahani and Piya Ka Ghar.
