The nitnem is laid down in the Sikh Rahit Maryada that every Sikh should daily recite japji, japu sahib, rehras and Soihila. But don't confuse this hukam with ritualism, it's not the reading that's important, it's the understanding and application in everyday life. If you a having issues due to time or in conflicting with your duties, try to learn them by heart or just recite the mool mantar, but do so with pure devotioon. This bliss can also be obtained bu nam simran. There are various ways in which a Sikh becomes enlightened. For example, if one was to go to Boali Sahib gurdwara, they will see that Sri Guru Amardas Ji states that one should bathe in the Baoli and recite the japji 84 times to obtain release from the cycles of birth and death. It's not the number of times that's important, it's submitting to wahereguru.....as in, one can do it 84, 94 or even 184 times withiut pure devotion , which don't equal a person doing it just once with a pure heart and dhian.
