the world of psychic energy and thoughts have their own reality. whatever people think about you makes a difference in your life. the difference could be small or big depending upon the intensity and amount of energy you receive.
some people are very vulnerable to evil eye. they catch the negativity from other people very easily. people who have the power to curse are often called as people with black tongue. because whenever they speak negative, it materialize quickly.
there are many dimensions of reality. only a psychic or a yogi can access other dimensions. e.g. very few people learn the art of seeing aura (second body of human being). whenever any disease comes to your physical body then it first appear in your aura few months ago. if that time any psychic sees your aura then he can tell you in advance that your particular body part is vulnerable to disease. the aura can be photographed also using the kirlian camera which was invented way back in 1939.
same is the case with psychic energy. if lot of people think good or bad about you then that energy starts collecting in your other body (emotional body or etheric body). sooner or later the energy will manifest in your life. it might take different time for different people. because we all have different set of karma, the strength of aura also varies from person to person. so the time will always vary but the energy will always manifest.
so make sure you don’t get any negative vibes from anyone. don’t hurt any one or cheat any one. do good to others. help them in need so that their blessings counter any negativity you might have to face in future or you might be carrying in your aura. the blessings of sages are very potent and powerful. their effect is more lasting and can totally transform your life. it is also believed that never take curse from someone who is in lot of pain because he can easily pass lot of painful energy to you. this is very logical also since the person is full of pain so he can only give pain to you. if you want blessings then visit a sage who is overcharged with positive and spiritual energy.
in indian tradition, we always try not to take curse from eunuch because their words also considered very powerful. might be because their energy is not leaking or getting wasted in sex.
in case someone sends you negative energy then if you can stay centered or totally still from within then that negative energy will be transformed into positive vibrations. love is another antidote or you have to create a positive shield around you or visit a charged temple or practice your spiritual sadhana.
make sure people have right image about you in their mind. because whenever they remember you they connect with the image which they have in their mind about you and thus you get the corresponding energy. thats why in terms of psychic energy, its good to have a clean image in public life.
lastly, have a good self esteem because what ever you think about yourself is also creating energy form around you. when you meet someone then subtly or unconsciously they can catch the energy form (or auric field) around you and will respond to you in same way. so if someone is not giving importance to you then one of the many reason is that you are not projecting good energy around yourself.
the world of psychic energy is a big topic but the essence is that we are surrounded with all forms of energy and its best to to attract positive or spiritual energy towards you.
