Control the mind perfectly. Fix the mmd at the lotus feet of the Lord. This is the very gist of Yoga. God is the friend of the poor and the helpless and the shelter of the distressed. This world which consists of friends, enemies, neutrals, which affects you with pleasure and pain, is only a creation of your mind which is a product of ignorance. Power, beauty, fame, prosperity, strength, fortitude, are manifestations of the Lord. Mind is responsible for the feelings of pleasure and pain. Control of mind is the highest yoga.
If you are always living in the awareness of this certainty of ‘one day I have to go’, would you ever neglect your spiritual Sadhana?
