Sahej or Sadharan Paath is the complete reading of the Sri Guru Granth Sahib from start to finish, accomplished at the reader's on pace. A Sahej Paath may be fulfilled by one or more readers. The pace of the paath is undetermined and will depend entirely on the reader(s).
Some dedicated Sikhs who have the Guru Granth Sahib installed at their home, carry out a Sahaj paath on a continuous basis at home. They begin one Sahaj Paath and in some cases, they take up to one year to read the whole of the Holy Granth. After they have carried out the bhog of the paath, they begin another paath. So in this way, they are continuously reading Gurbani at home for a little while, perhaps, on a daily basis.
Paath: This is any reading of the text of the holy Sri Guru Granth Sahib.
