Stop identifying with your physical body. Your physical body is not you – it is nothing more than your vehicle.
The reason why so many human beings lose their bearings and fall apart is that they continually identify with what they are not. The body, physical matter, is subject to decay, and if you identify with it, you too will decay.
Whereas if you identify with your immortal spirit, you become a spark, a flame, and you can overcome all difficulties.
Human beings do the greatest harm to themselves in their willingness to identify with corruptible, ephemeral matter instead of identifying with the spirit, which is immutable and eternal. When the spirit leaves the physical body, it continues to exist.
The physical body is merely the instrument that has been given to the spirit so that we might live on earth.
