“By vichara or discrimination you should distinguish the Real from the unreal, the imperishable from the perishable. The perishable and changing nature of the world attracts you so much, but does not give you any peace. So, instead of involving yourself in the impermanent and changing things, attune your mind always to the Real-the imperishable Truth. Attachment to the perishable brings distraction and sorrow.
To detach the mind from worldly objects, vairagya or dispassion is necessary. Without vairagya the mind will repeatedly run after worldly objects and you cannot have any concentration on God. To control the mind you should constantly direct it towards the divine. This requires continuous practice.”
