What is the highest remembrance? Not this or that 'thing' - not even the safeguarding of religion. The highest remembrance belongs to God. In times of stress or religious antagonism, hatred for others or hatred from others - only one Name can save us and that is the Name of God.

'Bhaj mann mere eko naam. Jeeya tere kai aavai kaam. Raini dinas gun gaayu ananta. Gur poore kaa nirmal mantaa' (Sri Guru Granth Sahib Ji 193)

Trans: 'Meditate, O my mind, on the One Name. It alone will be of use to your soul. Night and day, sing the Glorious Praises of the Infinite God, through the Pure Mantra of the Perfect Guru.'
