The directive to ensure full attendance comes amid instances of lack of quorum in both Houses.
Modi told the BJP parliamentary party meeting that he can do anything for the MPs but he cannot mark their presence.
"Being present in the house is the basic responsibility of the members," a BJP leader at the meeting quoted Modi as saying.
During the BJP Parliamentary meeting in the national capital on Tuesday, Union Minister for Information and Broadcasting M Venkaiah Naidu praised Yogi Adityanath, newly elected CM of Uttar Pradesh, for "garnering accolades all over."
Meanwhile, PM Modi also asked the Parliamentarians to thoroughly understand GST (Goods and Services Tax) system and explain it to the people in their respective constituencies.
At a recent event, PM said people should make efforts to discuss and understand the new indirect tax regime as it heads for a July 1 rollout
"I want the entire country to discuss and try to understand GST," Modi said here at the India Today Conclave through video conferencing.
Last week, Modi told BJP MPs that he would neither sit idle nor allow party leaders to do so and announced a set of programmes that would require all members to work at the booth level with an eye on the 2019 Lok Sabha elections.
" Na baithoonga, na baithne doonga (Neither will I sit nor allow anyone else to sit)," the Prime Minister said at a closed-door weekly meeting of party MPs on the Parliament premises.
He also told the MPs about a "remarkable change" in the perception of the people about his government. According to Modi, initially people felt that "the government is doing something" but now it had changed. "Now they believe the government is performing," he said, adding he would continue to work tirelessly to fulfil the people's expectations.
