Advaita and Worldly life

‘Advaita [non-duality] should not be practised in ordinary activities. It is sufficient if there is no differentiation in the mind. If one keeps cart-loads of discriminating thoughts within, one should not pretend that all is one on the outside.

‘Westerners practise mixed marriages and eat equally with everyone. What is the use of doing only this? Only wars and battlefields have resulted. Out of all these activities, who has obtained any happiness?

‘This world is a huge theatre. Each person has to act whatever role is assigned to him. It is the nature of the universe to be differentiated but within each person there should be no sense of differentiation.’

Bhagawan Ramana Maharishi

Sadhana -- a battlefied

Sadhana is a battlefield. You have to be vigilant. Don't take delivery of wrong beliefs and don't identify with the incoming thoughts that will give you pain and suffering. But if these things start happening to you, fight back by affirming, 'I am the Self; I am the Self; I am the Self;'.
These affirmations will lessen the power of the 'I am the body' arrows and eventually they will armour-plate you so successfully, the 'I am the body' thoughts that come your way will no longer have the power to touch you, affect you or make you suffer.
