Human Effort and God's Grace

Whether one likes it or not, accepts it or not, realizes it or not, nothing happens or materializes or realized without Human effort and God's Grace. The whole life of humans revolves around this divine law. 

There is no success without this combination as depicted in  Bhagavad-Gita. The following Shloka says, wherever there is Krishna, the Lord of Yoga and the archer Arjuna, Victory/Success is certain.

यत्र योगेश्वरः कृष्णो यत्र पार्थो धनुर्धरः ।
तत्र श्रीर्विजयो भूतिर्ध्रुवा नीतिर्मतिर्मम ॥ 18-78॥

Here Arjuna represents Human Effort; but human effort alone is not enough for success; Lord Krishna represents the Divine Grace that supports the effort and completes it. 

It also implies that human will should be in tune with God's will for the Grace to descend. Therefore the need for one to tune with His will. Nothing happens without His will. 

It also teaches us that one should live a life that attracts the Divine Grace by moulding one's life according to the divine principles or following the heart/inner voice within.

Yoga-Abhyas is all about our effort to attract His Grace. Grace is something that happens irrespective of one's deservingness. 

It does not happen just because we desire. Even to desire Grace, we need to deserve; and one who desires generally does not deserve; and one who deserves generally does not desire. 

We do not desire His Grace, we wait for His Grace while we work for  our deservingness.
