Knowledge of the Reality will show you that Bhakthi, Seva and Dharma are all one and indivisible. Without that knowledge, selfless service etc., become mere exercises in hypocrisy. But consciousness of Deva instead of Deha, of God instead of body, will bring forth the splendour of Prema. With that as inspiration and guide, man can achieve much good without even knowing or proclaiming that he is selfless in outlook. For him, it is all God's Will, His Leela, His Work.
Light is wisdom.
Without Light, all is Darkness. If you have not secured the lamp of Jnana to illumine your path, you stumble along in the gloom with Fear as your companion. There is no falsehood greater than Fear, no Ignorance mightier than that. Decide therefore to travel in the daylight of Jnana and be worthy of this human birth. Through your success, you can even make the lives of others worthwhile.
