Sikhism
Sikhism advocates the pursuit of salvation through disciplined, personal meditation on the name and message of God, meant to bring one into union with God. But a person's state of mind has to be detached from this world, with the understanding that this world is a temporary abode and their soul has to remain untouched by pain, pleasure, greed, emotional attachment, praise, slander and above all, egotistical pride. Thus their thoughts and deeds become "Nirmal" or pure and they merge with God or attain "Union with God", just as a drop of water falling from the skies merges with the ocean.
