A Sadhaka should first learn about the spiritual path from some great soul, then methodically follow it. If he does it haphazardly, he cannot achieve much success. Again, if he gives it up, he will have to put forth double the usual effort to gain the desired result. But no endeavour is lost. Lust, anger and greed gradually leave him who leads the spiritual life. Don’t waste your time anymore. Now the senses are strong and must be kept under control. This is no doubt a troublesome task. But practice Sadhana continually for seven or eight years; then you will enjoy the fruits of your practices, and peace and bliss thereof. Is meditation an easy affair? Only regular practice will bring perfection in it. Remember, it is next only to Samadhi. Self-surrender and everything will manifest from within through your Sadhana. Leave everything to God. Resign yourself wholly to Him.
