We can realise Truth when we remove the thought "I am the body".

Bhagavan says Loka Shoka Nirmoolyayai, which means the remover of sorrows and sadness. We have to eradicate our unhappiness. How? Through reading spiritual books, pondering over their meaning and by putting into action whatever we have learned, it will be removed.
No doubt, we can read, recite or memorize any of the Gita’s slokas. What is the use of this mastery? We have to try putting into practice what we have learned. It will surely free us.
