Faith is not something easily understandable. It is very enigmatic and entangling. Its definitions and interpretations undergo variations with every passing day. Scholars define it as a remembrance in heart, expression by tongue and practice by bodily organs. The definition of faith differs according to the different religions of people. Christians may differ from Jews in defining it and Muslims may differ from Hindus in defining it. But what is common tenet among all these religions is that faith is personal and does not subscribe to the outside conventions and traditions. One may appear great to people but bad to lord and vice versa. One may be near to lord but far away from people or close to people but distant from lord. One can personally develop long lasting relation to lord without others knowing it. Faith is something that can`t be demonstrated to anyone and proved to them that it is faith. It is an abstract idea that is very confidential between lord and his adherent. It is a motley of different beliefs and ideas that one subscribes to .
there are some fixed norms that one needs to adhere to to qualify for having faith. These norms should not be violated . These constitute the core of faith. For instance, one should not lie. One should not harm others unnecessarily. One should not commit adultery. One should not thieve. One should not harbor jealousy, envy, hatred and rancor to others. there are other various things that one needs to stick to if one wants to qualify for faith. These norms bind the faithful from doing various things.
Spiritual crises arise when these norms are violated. One despairs over the infringement of these norms and enters into the critical zone. In the fit of passions , one commits sins and feels joyful for a moment but soon after it pinches his heart and saddens him. The hangover of sins stays for long till one recovers it by repentance.
Question definitely arises why do you feel despaired if you do something wrong. This is a common question and people wonder why it is so. Humans have been created in such a way that their soul, that pleases or displeases, attains calm if it occupies the love and devotion of lord. Its attains pleasure by the remembrance of lord. If your soul does not taste the love and devotion of lord, it becomes restless and leaves you baffled by agony and anxiety.
Although, it is not so easy to persist in this way and it does not mean that once you fall, you cant get back at your feet. The doors of coming back never close. It is always open. Its entrance is repentance. Repentance heals the wounds of soul and pushes you back to your previous position. Don't lose hearts if you stumble in this way. Repent your sins. Come back to your lord and start doing things that please him. That convinces him to pardon you. To rid your despair and bless you with the directions to pray more lovingly.
