According to oral tradition, Guru Gobind Singh wrote one extra Svaiya that concludes the famous 33 Savaiya composition within the Dasam Guru Granth. This extra passage is not in the current printed version of the Dasam Guru Granth, but can be seen in a few old saroops of Dasam Guru Granth, noted by both Giani Sher Singh and through the research of Udasi Harnam Das. The tradition holds that Guru Gobind Singh wrote this concluding svaiya upon reaching Nandar in the later years of their life, and is meant to expound upon the highest state of enlightenment.
ਜਿਸ ਕੇ ਮਸਤਕਿ ਗੁਰ ਹਾਥੁ ਧਰ੍ਯੋ, ਵਹੁ ਜਾਨਤ ਹੈ ਸਭ ਕੇ ਘਟ ਕੀ ॥
The one who's forehead has received the touch of the Guru's hand, knows the inner mysteries of all existence.
ਅੰਤਰਿ ਗ੍ਯਾਨ ਪ੍ਰਗਾਸ ਭਯੋ ਹੈ, ਆਸਾ ਮਨਸਾ ਸਭ ਛੁਟਕੀ ॥
Within them the light of wisdom shines forth, their hopes and desires have all faded away.
ਆਤਮ ਚੀਨ ਪਰਾਤਮ ਚੀਨ੍ਯੋ, ਫੋਰ ਦਈ ਭ੍ਰਮ ਕੀ ਮਟਕੀ ॥
They have recognized their Self as the Highest Self, the container of doubt which has encased them has been broken in an instant.
ਦੂਖ ਸੂਖ ਸਭ ਤ੍ਯਾਗ ਦਯੋ ਹੈ, ਰਾਮ ਰਸਾਇਨ ਸੇ ਅਟਕੀ ॥
Pain and happiness have both been transcended; being imbued with the flavour of the Omnipresent these afflictions have been stalled.
