The Science of Work..
The kind of work as per ones nature, how passionate you are towards your work and the level of commitment, these three things lead to failure or success in that work. The material nature is a produce of the Three modes of nature - the mode of goodness, the mode of passion and the mode of ignorance. According to Vedanta, the living entity under the influence of these 3 modes of nature develops a particular kind of nature and should work accordingly as per his nature. From scientific angle and as per the Vedanta theory there are 5 causes for accomplishment of all actions - the physical body, the soul, the various body senses, different kinds of endeavour and the super soul. But there are 3 more factors that motivate action - knowledge, understanding and the object of knowledge. Unless you do not have the knowledge on what the action is to be performed, the object which is involved, and the right understanding by which one knows what is to be done and what is not to be done, what is to be feared and what is not to be feared, what is binding and what is liberating, right action can not be performed and completed.
An important factor which can not be neglected is that a living entity has to perform action as per the nature acquired by him. A soldier can not become a school teacher and a school teacher can not go on the war front to face gun fire. Every individual should adopt the kind of work which suits his nature. As Lord Krishna says that he has already divided the society in 4 major divisions- a) The Brahmin (teaching class), the Kshatriya (protectors), the vaisya (traders/merchants) and the Shudra (workers), the living entity acquires a particular nature under the influence of the three modes of nature and develops a skill accordingly. Success or failure in any work is related to many other factors and circumstances also.
If I go a little deeper, according to Yog Vasisht - There is no division between mind and action, before it is projected as action it arises in the mind, with the mind as its body. Action is nothing but the movement of energy in consciousness. When such action comes to an end, mind comes to an end too. It clearly means the source of all action good or evil is mind alone. Karma or action takes different forms in different circumstances. The gold in ornament is said to be an ornament but still it is gold. Karma in different surroundings may change but still it is karma. Pure movement in consciousness is karma or action without an independent doer. When it pursues the fruition of action it is known as karma. When it entertains the notion "I have seen this before", it is known as memory. When the effects of past enjoyment continue to remain, it is known as latent tendencies. When it is consciousness of the truth that the vision of division is the product of ignorance, it is known as knowledge. When it moves towards greater self - forgetfulness and deeper involvement in false tendencies, it is known as impurity. When it entertains the in dweller with sensations it is known as senses, when it creates confusion between reality and appearance it is known as Maya. When it thinks I am bound, there is bondage. When it thinks I am free there is freedom. The Vedic texts talk about The entire universe to be within the mind, even the notions of bondage and liberation. Neither the body nor the enlightened being actually undergoes suffering. It is only the ignorant mind that suffers. It is only in a state of ignorance that the mind dreams of the world appearance , not when it is awakened or enlightened. In all experiences of happiness and unhappiness, as also in imaginations and hallucinations, it is Mind that does everything and it is mind that experiences all this. Mind is Man.
