There are all sorts of fear: fear of death, fear of old age, fear of disease, fear of losing wealth, fear of losing position, fear of enemies, fear of opponents, fear of losing dear ones, fear of examination, fear of evil spirits, fear of public criticism. There are also unnatural fears, or phobias, such as snake-phobia, rat-phobia, height-phobia, claustrophobia, you name it! Phobias are endless.
Fear is caused by attachment to the body and to outside objects (fame, money, property, dear ones, etc.). Anxiety is the effect of fear.
One of our greatest fears is the fear of death—we know this physical body will eventually cease to function. The best way to overcome this fear is to realize the essential indestructibility of your own inner Spirit. This realization will not only conquer fear but also confer bliss and peace. Once you experience your own inner Spirit, fear leaves you; there is no fear in the innermost Spirit. So take refuge in your Spirit within.
According to the law of conservation of energy, it is impossible for energy (Spirit) to be destroyed. Hence, there must be a rebirth. Just as we move from one house to another, so also the Spirit passes from one physical body to another. Commenting on rebirth, world-renowned Swami Sivananda of Rishikesh, India said: “If we deny pre-existence and rebirth and take into consideration that life begins with this birth only and ends completely with the death of the body and there is nothing more, then it will be no compensation for the virtuous man who has done noble actions and for the wicked man who has done crimes. The chain of cause and effect, antecedent and consequence, will be broken abruptly. There will be terrible injustice everywhere.” (quoted in Building a Noble World, p. 15)
Logically, mathematically and scientifically, it is clear that energy (Spirit) is indestructible; the form may change but the substance never changes. The mind and the physical body, with its various senses, are merely the outer shell that houses the innermost Spirit.
Although everyone has this immortal inner Spirit, very few people tune in to it. What gets in the way of experiencing the ever-present inner Spirit? Weaknesses of the mind: anger, greed, hatred, malice, lust, jealousy and pride. Once this “dust” in the form of various weaknesses is removed from the “mirror” of the inner Spirit, the mirror shines forth and the inner Spirit is experienced. This Spirit is birthless and deathless. Beyond the mind lies the transcendental experience of the Spirit within. This Spirit is always free from fear.
How do we experience this inner Spirit? Meditation is the most powerful method. Meditate on the Spirit within to completely overcome your fear of death.
The basic cause of fear is lack of faith in one's own eternal Spirit. Contemplate well: from where does your fear arise? The mind thinks in words. These thoughts, if focused on the negative, create fear. If you change your fearful thoughts into fearless thoughts, you can overcome your own fear. Wrong understanding causes fear. Fear never does any good, does it? Get rid of all imaginary fears.
There is absolutely no need to be afraid of death. Be fully assured you won't physically die until your time of death has arrived!
Reciting the holy mantras produces spiritual vibration, which can cure all sorts of mental fears.
Hope this helps. May you be free from fear!
