हिंदी अनुवाद - स्वामी रामसुख दास जी ( भगवद् गीता 5.27)
।।5.27  5.28।।बाह्य पदार्थोंको बाहर ही छोड़कर और नेत्रोंकी दृष्टिको भौंहोंके बीचमें स्थित करके तथा नासिकामें विचरनेवाले प्राण और अपान वायुको सम करके जिसकी इन्द्रियाँ मन और बुद्धि अपने वशमें हैं जो मोक्षपरायण है तथा जो इच्छा भय और क्रोधसे सर्वथा रहित है वह मुनि सदा मुक्त ही है।


Rudra Vaishnava Sampradaya - Commentary




In verse twenty-four of this chapter Lord Krishna stated that a yogi
attains the Brahman or spiritual substratum pervading all existence. Now
the method of that yoga or science of the individual consciousness
attaining communion with the ultimate consciousness is now described in
brief. External sense objects enter the mind when one thinks about them, so
one must not think about them. Fixing the gaze up between the eyebrows is
done to focus them because if the eyes are fully closed then the mind may
fall asleep and if the eyes are wide open they may look here and there at
objects, so in order to avoid both these defects one focuses the gaze with
eyes half closed between the eyebrows or the tip of the nose.  Suspending
the breath means to harmonise the prana outgoing breath with the apana or
incoming breath until they both become suspended and by the control of
breath the mind and senses become controlled. Such a person who has moksa
or liberation as their only aim are indeed always free from the material
existence even while living in the material world.


Brahma Vaishnava Sampradaya - Commentary





In  these  two  verses  Lord  Krishna  describes  the  perfected  method  of
meditaion for achieving atma tattva or realisation of the soul and moksa  or
liberation from material existence. The method commences by  turning  inward
with the mind away from all external sense objects  associated  with  sight,
sound, taste, smell and touch. Then one fixes the vision internally  between
the eyebrows while simultaneously slowly restraining the inward and  outward
breaths until they merge into one and pause themselves of their  own  accord
in the state know as kumbhaka.





Now begins the summation.





The one who has not received moksa or liberation while  aspiring  for  moksa
nevertheless has acquired qualities aspiring for moksa.  Thus  human  beings
acquiring the qualities of moksa acquire spiritual knowledge and  eventually
achieve moksa by this spiritual knowledge.


Shri Vaishnava Sampradaya - Commentary


Stopping all activities of the external senses prepares one to qualify for
practising meditation. Sitting in an erect posture, focusing the eyes half
closed between the eyebrows or the tip of the nose, equalising the breath
until suspended rendering the mind and sense incapable of moving to any
other location except to the atma or soul. Due to fulfilling the above
meditation one is automatically freed from desire, fear and doubts. Whose
sole goal and aim is moksa or liberation. Determinedly intent on achieving
atma tattva or soul realisation such a person is considered to be liberated
even before fully accomplishing the goal as it is a certainty it will be
achieved. The ease which this karma yoga or selfless performance of
prescribed Vedic activities with its nitya or daily duties and its
naimitika or occasional duities having yoga or the science of the
individual consciousness attaining communion with the ultimate
consciousness will next be revealed.
