Personality is that cosmic endowment, that phase of universal reality, which can coexist with unlimited change and at the same time retain its identity in the very presence of all such changes, and forever afterward.

The man whom these torment not, O chief of men, balanced in pain and pleasure, steadfast, he is fitted for immortality. The unreal hath no being; the real never ceaseth to be; the truth about both hath been perceived by the seers of the essence of things. Know That to be indestructible by whom all this is pervaded. Nor can any work the destruction of that imperishable One.
Even here on earth everything is overcome by those whose mind remains balanced; the Eternal is incorruptible and balanced; therefore they are established in the Eternal. With Reason firm, unperplexed, the knower of the Eternal established in the Eternal, neither rejoiceth on obtaining what is pleasant, nor sorroweth on obtaining what is unpleasant. He, whose self is unattached to external contacts and findeth joy in the Self, having the self harmonised with the Eternal by yoga, enjoys imperishable bliss.
Uncleavable he, incombustible he, and indeed neither to be wetted nor dried away; perpetual, all-pervasive, stable, immovable, ancient. Unmanifest, unthinkable, immutable, he is called; therefore knowing him as such, thou shouldst not grieve. Or if thou thinkest of him as being constantly born and constantly dying, even then, O mighty-armed, thou shouldst not grieve. For certain is death for the born, and certain is birth for the dead; therefore over the inevitable thou shouldst not grieve.
