SAMPAT PAATTH
It means: to combine a sentence or verse either in the beginning or in the end of a Mantra. It is done to add value or increase importance of that particular sentence or verse. This is a Brahminic style of reciting of the mantras.
The Nirmalas (who are students and followers of Brahmin pujaris of Varanasi) have introduced this style into the recitation of Guru Granth Sahib too. In this recitation a specific line from Guru Granth Sahib is recited after reading of each stanza/salok. Thus, this specific line gets recited for thousands of times. This is, in fact, sacrilege of Gurbaani. Gurbaani is not a Mantar (incantation); thus, treating the specific line, which is recited repeatedly, as Mantra is an act of sacrilege. Hence, Sampat Paatth is against Sikh philosophy. Those, who are under the impact of the Brahmins, perform such practices.
Similarly, so-called Sankat Mochan Shabads (literally: those hymns which pull out troubles) too are against Sikh thought. These practices are against the basic principles of Sikhism.
