Supreme goal denote the state of liberation ,which is the highest object worth attaining ,the attainment of which leaves nothing to be attained ,and which brings the total cessation of all forms of suffering as soon as it is attained. Therefore ,supreme goal is the absolute formless divinity ,the embodiment of truth ,knowledge and bliss ,who is spoken of as supreme indestructible.
The Supreme abode mentioned in this verse stands for the Lord's eternal abode,His very being and his divine state.There is no difference between the attainment of the eternal abode of God, of the divine state and of God himself.Diversity of fruit exists only in the eyes of practicants following different path of discipline.Attaining the supreme goal there is no return to this mortal world.
The entire creation consisting of sentiment and insentiment beings is part and parcel of God,has emanated from God and on God alone does it rest. Just as air, fire ,water and earth are all pervaded by ether, even so the entire creation is pervaded by God . Surrendering everything to God ,who sustains all and is the inner witness of all ,remaining supremely contented at all times with his dispensation ,and constantly thinking of him with undivided love in every way through exclusive devotion can reach him easily.
In this verse Lord talks to Arguna about the two paths in which the yogi departing is in a state of return and the other path the state of no return. The Lord undertakes to reveal to Arjuna the difference between the two paths,one leading to the regions from which one has to return and the other leading to a state of no return.
Of the two paths the one is that in which are stationed the all-effulgent fire god and the dieties presiding over daylight,the bright fort night, and the six months of the northward course of the sun respectively;proceeding along it after death yogis ,who have known brahma, being successively led by the above gods , finally reach Brahma.
The other path is that where in are stationed the gods presiding over smoke,night, the dark fortnight,and the six months of the southward course of the sun; the yogi devoted to action with an interested motive taking to this path after death is led by the ab ove gods ,one after qnother ,and attaining the luster of the moon and enjoying the fruits of his meritorious deeds in heaven returns to this mortal world.
