According to Patanjali, Chit–Nirodh ( cessation of mental waives) is Yoga. Debacling the mind or mind stuff which is a repository of feelings, attachments, aversions and memories etc., is essential to visualize or realize the divine one that exist behind all those sensory experiences. Bhakti Yoga, Karma Yoga, Jnana Yoga and Raja Yoga are of course different paths adopted or taken by people according to their own gunas (leanings). However all these tracks are to have the basic yogic principles to be fruitful. Ethics a primal aspect of spirituality, Control a rudimentary step of Yoga and Purusharth (feeling of part of divine) a powerful conscious driving of supreme human efforts, all these are basics of Yoga practice.
Removal of obstacles that leads to a perfect concentration is meditation. Major obstacles observed in human beings are: Sickness, lack of energy, doubt, lack of firmness of mind and erroneous perception.
Sickness: Yoga must be healthy, it is only when you are healthy that you forget about the body while pursuing something vigorously. Unhealthy body demands attention and thus takes away consciousness from a higher plane to a physical one. For Yogis, nothing is more disdainful than a non-pliant body. Unhealthy body cannot be reduced to a tool or a vehicle. Human body is an artifact that must be polished, prepared and used for launching into infinite possibilities.
Lack of Energy: This is one of the biggest obstacle. Causes could be numerous, but Yoga is not meant for a timid hearted. No doubt this is path is called a Royal Path. Ascension of the ordinary mortal to a supreme being is of course a spiritual coronation and it demands bravery. Divine providence is there, one must consciously scratch its surface, it shall usher in energy. Energy is all in Yoga, sustained perseverance is quintessential.Only the brave ones ravish this earth. So be a Yogi and assert.
Doubt: One must have faith in what what one undertakes–could doubt or reject having experienced it, however prior to that one must move with faith. Faith is a confidence in oneself and confiding in the aim. One must see the goal as an extension of oneself. Yogi must see himself as a yogi, must move with the premise that he is what he is trying to be.
Unstable mind: What causes it? Past opposing the present is the evil behind this phenomena. A collection of impression and unworked karmas, extreme feelings and things experienced without compassion are some of the reasons that the subconscious mind becomes a subculture of these distracting habits. Mind must be brought to stand still. Ways of doing it either hold the mind itself or otherwise hold the Prana, the breath that sea-saws the mind.
Erroneous Perception: Attaching wrong priorities, not being able to discriminate between objects. Not discerning the principles of life as to its transitory nature. Attachment and day dreaming, trying to create a clay hut to reside in and thinking that safety is permanent. One must have knowledge to see the ephemeral nature of life and human passions and emotions. Nature/Maya plays havoc and who life is spent in cravings and it is rightly so, for nature wants to procreate and perpetuate. However, Yogin wants to go beyond this, he must not be charmed by what nature wants to shower him with. Yoga and Bhoga (sensual enjoyments) does not go together. In Yogic life start with the basic principle that is–you belong to no one and no one belongs to you.
