You should know that is my form.
Explanation: This line has been taken from the first shloka of the poem by the same title. The God showers mercy upon all living being voluntarily and without any discrimination.
God himself says that I am not the king of Vaikunth or I am not Shiva, the lord of Mountain Kailash. Those who are dedicated for the welfare of the world and those who are benevolent and are engaged in various occupations are the form of mine.
The supreme power exists even in the smallest particle. In this poem, the poet has conceptualized different forms of God. The God says that his real form lies in different professionals like - farmer, weaver, mason, teacher, vaidya, scientist, saint and solider who are engaged in the welfare of all living beings and are doing their duty voluntarily without any pressure.
Thus, from this shloka we get moral that we should do our duty properly and should do welfare of all living being
