Indian philosophy has been classified according to those who believe in God and those who do not believe in God. But to the divinity, what counts are the qualities of men’s character rather than their beliefs. Prahlada, who was the son of a demon king, was one of the greatest devotees of the Lord. He was put to great trouble by his father and his teachers who tried to impress on him their demonic traits. Although he was born a demon, Prahlada always displayed a noble and sterling character. And despite all the difficulties he was put to, Prahlada was able to continuously enjoy the bliss of his own immortal self, and know the presence of the Lord in his heart. Prahlada means the one who is continuously happy. So, if you go on thinking of the Lord continuously, these feelings of joy will shine forth with an effulgent splendor, and you will become one with God.
Right at the outset of your spiritual journey you have to make determined efforts to control your desires and anger, your attachments and hatred. This will permit the divine principle to shine forth from within you. Controlling desire and anger is a most important spiritual practice. It is the primary task of every devotee. If you succeed in controlling desire and anger, attachments and hatred, you will be able to justify your life and reach your goal. But if you allow them to remain within you, then whatever spiritual exercises you undertake will be wasted and your life too will become an utter waste.
