BY THE GRACE OF THE TRUE GURU:
Yoga is not the patched coat, Yoga is not the walking stick. Yoga is not smearing the body with ashes. Yoga is not the ear-rings, and not the shaven head. Yoga is not the blowing of the horn. Remaining unblemished in the midst of the filth of the world — this is the way to attain Yoga. || 1 || By mere words, Yoga is not attained. One who looks upon all with a single eye, and knows them to be one and the same — he alone is known as a Yogi. || 1 || Pause || Yoga is not wandering to the tombs of the dead;
Yoga is not sitting in trances. Yoga is not wandering through foreign lands; Yoga is not bathing at sacred shrines of pilgrimage.
Remaining unblemished in the midst of the filth of the world — this is the way to attain Yoga. || 2 || Meeting with the True Guru, doubt is dispelled, and the wandering mind is restrained. Nectar rains down, celestial music resounds, and deep within, wisdom is obtained. Remaining unblemished in the midst of the filth of the world — this is the way to attain Yoga. || 3 ||
O Nanak, remain dead while yet alive — practice such a Yoga. When the horn is blown without being blown, then you shall attain the state of fearless dignity. Remaining unblemished in the midst of the filth of the world — this is the way to attain Yoga. || 4 || 1 || 8 ||
Translation is not perfect but pretty close to the Guru Message. It comes down to battle within, it starts with trying but eventually turns into a natural one(State of a mind). Even in JapJi Sahib, four realms are not addressed as any chakras or energy. Sikhism was and is a for masses, high techniques has no advocacy in any Guru Shabad. References are used just as references are found about Hindu mythology.
Please ponder over what Guru ji is saying in the context of Yoga .Others or mine views are immaterial in context of the above Guru Shabad that directly addresses "YOGA".
