"Some are born with the characteristics of the yogi; but they too should be careful. It is 'Lust and Greed' alone that is the obstacle; it makes them deviate from the path of yoga and drags them into worldliness. Perhaps they have some desire for enjoyment. After fulfilling their desire, they again direct their minds to God and thus recover their former state of mind, fit for the practise of yoga.
"Have you ever seen the spring trap for fish, called the 'satka-kal'?"
M: "No, sir, I haven't seen it."
Sri Ramakrishna: 'They use it in our part of the country. One end of a bamboo pole is fastened in the ground, and the other is bent over with a catch. From this end a line with a hook hangs over the water, with bait tied to the hook. When the fish swallows the bait, suddenly the bamboo jumps up and regains its upright position.
"Again, take a pair of scales, for example. If a weight is placed on one side, the lower needle moves away from the upper one. The lower needle is the mind, and the upper one, God. The meeting of the two is yoga.
"Unless the mind becomes steady there cannot be yoga. It is the wind of worldliness that always disturbs the mind, which may be likened to a candle-flame. If that flame doesn't move at all, then one is said to have attained yoga.
'Lust and Greed' alone is the obstacle to 'yoga. Always analyse what you see. What is there in the. body of a woman? Only such things as blood, flesh, fat, entrails, and the like. Why should one love such a body?
"Sometimes I used to assume a rajasic mood in order to practise renunciation. Once I had the desire to put on a gold-embroidered robe, wear a ring on my finger, and smoke a hubble-bubble with a long pipe. Mathur Babu procured all these things for me. I wore the gold-embroidered robe and said to myself after a while, 'Mind! This is what is called a gold-embroidered robe.' Then I took it off and threw it away. I couldn't stand the robe any more. Again I said to myself, 'Mind! This is called a shawl, and this a ring, and this, smoking a hubble-bubble with a long pipe.' I threw those things away once for all, and the desire to enjoy them never arose in my mind again."
It was almost dusk. The Master and M. stood talking alone near the door on the southeast verandah.
Sri Ramakrishna (to M.): "The mind of the yogi is always fixed on God, always absorbed in the Self. You can recognize such a man by merely looking at him. His eyes are wide open, with an aimless look, like. the eyes of the mother bird hatching her eggs. Her entire mind is fixed on the eggs, and there is a vacant look in her eyes.
