Hindrance of Supreme Enlightenment and Common Sense
Some buddhists whilst in meditation or buddhism mindfulness in daily living, caused hindrance to themselves by holding or focus on supreme enlightenment, omniscience or bodhicitta, and/or attainment. Although holding on to bodhicitta generates blessings, it does not develop merit for bodhicitta.
All non buddhists before attempting buddhism are hindered by its common sense or in Buddhism term is Alaya consciousness or the Eight consciousness or Storehouse consciousness.
The alaya consciousness or storehouse consciousness is the place where all the actions and experiences in this life and the previous lives generated by the seven consciousnesses are stored as karma, being the only consciousness which comes along with every birth. This consciousness influences at the same time the workings of the other seven consciousnesses.
We take this alaya consciousness with us in all our births in the various realms of existence. It contains the seeds of various types of karma, and it is the storehouse of the habitual evil karmic tendencies that we have cultivated for eons. Because of the karmic seeds contained in the alaya consciousness one may die a premature death, be stricken with unexpected disease or inexplicable misfortune, overcome by strong desires, aversions and obsessions, can think and do things that one should never even imagine, etc. So strong is the influence of the alaya consciousness. When Shinran is recorded as saying in chapter 13th of Tannisho: “a person may not wish to harm anyone and yet end up killing a hundred or a thousand people”, he is in fact referring to the influence of past karma contained in the alaya consciousness.
As the storehouse consciousness is not separated of bodhicitta or buddha nature. It is advisable to recall this buddha seed frequently through buddha name to replace or subsides all unkind thoughts, Buddha name is actually our own pure nature name, and/or in a relax mannerism, naturally residing in emptiness when in unkind encounters. Buddha name is an expedient terse method to recover from own purity peace. As buddha mentioned do not stay in the past and future, for present, be wisely pleasant and compassion with all matters, remember kindness, let go unkindness thoughts, avoid conflict, possessive and manipulating other. And according to The Treasure Collection Sutra, one in billions beings can't achieve enlightenment in the dharma ending era, besides pureland method.
