Simran


Simran is a Punjabi word derived from the Sanskrit word स्मरण smaraṇa, "the act of remembrance, reminiscence, and recollection," which leads to the realization of what may be the highest aspect and purpose in one's life. It is the continuous remembrance of the finest aspect of the self, and/or the continuous remembrance of God, thus used for introducing spirituality. This state is maintained continuously while carrying out the worldly works outside.

Gurmukhi

Simran is a commonly used term as a verb in Gurmukhi, which refers to 'meditating' of the Nām, or name, of God. Sikhism is a distinct faith, whereby God can be realized purely through individual devotion, without subjection to rites and rituals by priests or other intermediaries.
It says in the Guru Granth Sahib that through Simran one is purified and attains salvation or 'mukti'. This is because 'si-mar' means 'to die over', thus indicating to death of ego, allowing truth ultimate truth or sat to appear.
On page 202 of the Guru Granth Sahib, Guruji writes:
This hymn teaches a person who wishes to gain from this human life, one must attain a higher spiritual state by become free of attachment by realizing that all that is, is empty. Thereby, merit is acquired by devoutly repeating, comprehending and living by the sacred word every day so as to progressively reveal the divine and ultimate truth to the person who earnestly seeks it:
Guru Ram Das says in Sarang ki var :

Sant Mat

In Sant Mat the word Simran is used for the spiritual practice of repeating the mantra given by the Satguru during initiation. The mantra itself is also called Simran. Simran repetition is done during meditation and also outside it, however this mantra is later dropped in favor of real feeling of self or the God, which happens due to breaking out of monotony through Jap. Thus mantra is used only till the point, monotony and previously formed patterns are broken. After it pure Simran is carried by the sadhak.
