If you want to attain immortality, go beyond the pairs of opposites. Endure bravely heat and cold, pain and sorrow, loss and failure, censure and dishonour. You will attain equanimity of mind, peace and poise. If you are balanced in pleasure and pain, gain and loss, victory and defeat, sin will not touch thee; you will not be affected by the fruits of your actions
