Srimad Bhagavad-Gita :
Chapter-3. ( Karma-yogam)
These three properties of Prakriti’s gunas, which are distributed disproportionately in everyone and are never in equilibrium, decide the difference in one’s call of duty. If you are predominantly sattvic in nature, you will be fitted for one kind of work in this world; one type of participation will be expected from you in the scheme of things. If you are predominantly rajasic for some reason or the other, then you will be assigned some job, some work, some duty according to your particular temperament. But suppose you are basically unfit for other physical reasons, such as the preponderance of tamas, etc.; then, you will have to be taken care of in a different way altogether.
Everybody in this world has a duty to perform. You can ask me what this duty is, and why you should do anything. You should not put such questions such as why should you do and why should you not do. Your duty depends upon your automatic involvement in the cosmic setup of things, and so you are not simply saying you shall do or you shall not do. The cosmic setup itself decides in what manner you can be called upon to do your duty.
There are degrees and variety in the participation of an individual in the universal scheme, and each person seems to be different from every other person. No two individuals collide or unite to become one individual, though there are similarities. For instance, when we work in a single office, factory or organisation, it may appear we are all doing one uniform type of work, but that is only on the superficial level. Basically there is an independence and a distinction – without difference, we may say – even in a common setup like an office or an organisation, etc.
You are all students here. In a way, you are all uniform in your outlook, in your requirement and in your daily duty, but still you have an individuality of your own. One person does not totally merge into another person. Similarly, there is a tremendous variety in the call of duty, and yet it is rooted in a single unity of perspective.
