With sincerity and earnestness one can realize God through all religions. The Vaishnavas will realize God, and so will the Saktas, the Vedantists, and the Brahmos. The Mussalmans and Christians will realize Him too. All will certainly realize God if they are earnest and sincere.
You must know that there are different tastes. There are also different powers of digestion... different temperaments... differences in the capacity to comprehend.
God can be realized through all paths. All religions are true. The important thing is to reach the roof. You can reach it by stone stairs or by wooden stairs or by bamboo steps or by a rope. You can also climb up by a bamboo pole.
A man develops a subtle power as a result of the strict observance of celibacy for twelve years. Then he can understand and grasp very subtle things which otherwise elude his intellect. Through that understanding the aspirant can have direct vision of God. That pure understanding alone enables him to realize Truth.
When you meditate, go into the solitude of a forest, or a quiet corner, and enter into the chamber of your heart. And always keep your power of discrimination awake.
God reveals Himself to a devotee who feels drawn to Him by the combined force of these three attractions: the attraction of worldly possessions for the worldly man, the child's attraction for its mother, and the husband's attraction for the chaste wife. If one feels drawn to Him by the combined force of these three attractions, then through it one can attain Him.
If you feel proud, let it be in the thought that you are the servant of God, the son of God. Great men have the nature of a child. They are always a child before Him; so they are free from pride. All their strength is of God and not their own. It belongs to Him and comes from Him.
More are the names of God and infinite are the forms through which He may be approached. In whatever name and form you worship Him, through them you will realise Him.
Who may be called a paramahamsa? He who, like a swan, can take the milk from a mixture of milk and water, leaving aside the water. He who, like an ant, can take the sugar from a mixture of sugar and sand, leaving aside the sand.
