If you are unable to practise abhyasa too, be intent on doing actions for My sake. Even by doing actions for My sake, you shall attain perfection. (Bhagavad Gita Chapter 12 – Verse 10)
If both the methods mentioned (that is, the method of constant remembrance and that of repeated attempts to remember Bhagavan) are beyond your power, then devote yourself to works which please Me. For thus, working for My sake, you will become perfect, even without the practice of other forms of yoga or devotions. This is called the path of service or the path of action, karma yoga.
In Hindu scriptures we find mention made of special works performed to please Bhagvan. These include building of temples or places of worship, observance of fasts and feasts, singing hymns, performing charitable acts, and so on. Of course, such acts will purify the mind and the purified mind will be able to practise yoga. Through the constant practice of yoga the mind will become enlightened, and this will lead to perfection and freedom.
But for some, this also will be too troublesome or unattractive. Well, says Bhagavan Sri Krishna, you need not perform any special acts, for I look upon all work as the same. I do not care for the type of work. I am pleased with all work if the attitude in which the work is performed is right. The question with God is not what we are doing, but how we are doing it. It is not the work that is of much importance, but the motive. So, if you do not wish to engage in special works that are pleasing to Me, in such works as are of benefit to My children, then I will show you still another way.
