Haridwar: Describing May 23, when the BJP rode back to power with a massive mandate, as a "historic" day, Yoga guru Ramdev Monday said it should be celebrated either as "Modi Diwas or public welfare day".

The BJP won 303 of the 542 Lok Sabha seats that went to polls this time while the opposition was left way behind with the Congress winning only 52 seats. The results for the seven-phase general elections were announced on May 23.

"May 23 is a historic day. It should be celebrated either as Modi Diwas or Jan Kalyan Diwas (public welfare day)," Ramdev told reporters here on the sidelines of a programme to launch milk and dairy products of Patanjali.

Narendra Modi is the third prime minister of the country who has been able to retain power for a second term with full majority in Lok Sabha after Jawaharlal Nehru and Indira Gandhi.

Speaking about Patanjali Ayurved Limited's latest line of products, the Yoga guru, who is the co-founder of the company, said Patanjali's toned milk, butter, paneer, lassi and chach were made from pure cow milk without any chemicals.

"These are cheaper and better than those of Mother Dairy and Amul," Ramdev said, without elaborating how Patanjali's products were better than those of its rivals.

He claimed other companies used a "chemical colour" in its butter which was injurious to health.

The dairy and milk products of Patanjali are being supplied to Delhi-NCR, Uttarakhand, Rajasthan, Mumbai and Pune in the first phase and plans are underway to supply these soon to other states, Ramdev said.

On Sunday, Ramdev addressing a press conference had opined that India is not ready to deal with its population explosion and suggested some measures like denying voting rights and other government services to the third children onwards.
