Lord Viṣṇu advised King Pṛthu that everyone should follow the principles of varṇāśrama-dharma; then, in whatever capacity one remains within this material world, his salvation is guaranteed after death. In this age, however, since the system of varṇāśrama-dharma is topsy-turvy, it is very difficult to strictly follow all the principles. The only method for becoming perfect in life is to develop Kṛṣṇa consciousness.
