While practising sadhana, one must follow the rules laid down in scriptures or follow the commands of the Guru or that of God. While following these rules or commands, one should not worry whatever obstacles come. Continue with one’s prescribed sadhana and achieve success, even at the cost of one’s life. Some people say that they are following Swami’s commands, but they are facing many obstacles in their sadhana. This is not the correct attitude. In fact, if one follows Swami’s instructions carefully and correctly, no obstacles will come. If obstacles come, it means one has not followed the commands correctly! Before undertaking sadhana, there are certain things which one should know. Sadhana refers to an activity undertaken for achieving one’s goal or purpose in life. The sadhaka has to decide what he wants to achieve, what his purpose is. Then sadhana has to be carried on until one achieves that goal. If one undertakes sadhana without knowing these aspects, one will falter, and face obstacles and problems. Then one may lose faith in the guru, which could result in a total fall and destruction of oneself. So, one must be very careful about doing sadhana.
