Our mind wants everything and the only thing it dislike is discipline
and Meditation is the art of gaining more and more control over mind.So
it is obvious that mind will play game so as not to get discipline and
create various kind of obstacle in practice of meditation.
While there are various kind of obstacles, the most common type are listed below for your reference.
1) Spiritual pride
The practitioner some time has few experience or powers and filled with
pride. He may try to separate himself from others thinking himself as
superior. This pride is a serious obstacle in the path of experiencing
the truth.
2) Motives of acquiring powers
Some practitioners have hopes of acquiring powers and their motive
results in attachment to such powers, which is a serious obstacle.
3) Doubt
When practitioners have unrealistic expectations ,it results in doubt
for example the beginners thinks that the kundalini will be awakened
quickly and he would be filled with powers also when his faith get
weakened up he try to leave the practice.
4) Laziness
Laziness often effect practitioners in the beginning.
5) Sleep during meditation
Some times practitioners get into sleep during meditation in initial stages.
6) Health
Sometime practitioners do not do exercises and does not realize that
physical body is the vehicle for attaining the truth and can be
attained by strong body or some time practitioners torture the body by
not taking medicine at the time of illness.
7) Overeating
Practice of overeating leads to heaviness and results into sleep during the meditation.
8) Food
The kind of food we eat directly affect our mind apart from our body.
If we eat food which is Tamasic food or Rajasic for example food with
lot of chilies, or eating quickly or bitter or stale, all these kind of
food leads to obstruction in the practice of meditation
because of its nature.
Those who practice regularly knows that the practice of meditation
always go in cycle.Sometime it will be going very good and smooth and
sometime it just does not happen and this is the time when practitioner
has to be cool and calm and accepting the fact that it just happen and
it will be over and keep going and practicing and not to get frustrated.
