Sree Sree Guru Gaurangau Jayatah!
There are two paths: ”Pravritimarg” (Path through married life) and ”Nivritimarg” (Path through unmarried – ascetic life). Generally people are eligible for "Pravritimarg". Persons who have made up their minds that they will never go to house hold life (worldly life) are only competent to take the ascetic order.
You should not wait for your decision that in future whether you will accept married life or unmarried life, you should start Bhajan immediately (Chanting of the Holy Name, etc. avoiding tenfold offenses) because, nobody knows when we shall have to leave this world. When Srimad Raghunath Das Goswami was very eager to surmount this worldly ocean, Lord Sree Chaitanya Mahaprabhu pacified him by first saying that he should not become mad, and that at present he should remain in his house with a restful mind. Nobody can surmount the ocean of births and deaths all of a sudden, it will take time. Gradually he can surmount it. He should not try to show outwardly his indifference to worldly affairs; inwardly he should practice abnegation and worship Sree Krishna with sincerity. Sree Krishna will rescue him from the pangs of worldly suffering in no time.
