Sometimes we are entrapped by some feminine attraction. These are impediments. So we may not be able to make complete progress.
So Kṛṣṇa says that, "My dear Arjuna," na hi kalyāṇa-kṛt kaścid durgatim, "anyone who has attempted even one percent sincerely culture of spiritual realization, he will never fall down." "He will never fall down." That sincerity. Because we are weak, and the material energy is very strong, so to adopt spiritual life is more or less declare war against the material energy.
The material . . . the illusory energy, she is trying to curb this conditioned soul as far as possible. Now, when the conditioned soul tries to get out of her clutches by spiritual advancement of knowledge, oh, she becomes more stringent. Yes. She wants to test, "How much this person is sincere?" So there will be so many allurement offered by the material energy.
Now, there is a story. There are many stories. One of them I am citing. It is very interesting. Viśvāmitra Muni. Viśvāmitra Muni, he was a great king, kṣatriya, but his priest, Vasiṣṭha Muni, he had great spiritual power. So he renounced his kingdom. He wanted to advance. He was kingly, royal order, but still, he wanted to advance in the spiritual order. So he adopted yoga process, meditation. That time it was possible for adopting this process, yoga process.
So he was meditating in such a way that the Indra, who was the king of heaven, he thought that, "This man is trying to occupy my post." As there is competition . . . this is also . . . heaven means that is also material world. So this competition—no businessman wants an another businessman go ahead. He wants to cut down. Competition of price, quality. Similarly, that Indra, he thought that, "This man is so strongly meditating, it may be that I may be deposed and he come to my seat." Then he arranged one of his society girls, Menakā, to go there and allure this muni.
So when Menakā approached that ṛṣi, Viśvāmitra Ṛṣi, he was meditating. And simply by the sound of her bangles, she (he) could understand, "There is some woman." And as soon as he saw that is heavenly, celestial beauty, he was captivated. Then there was a result, that a great . . . Śakuntalā. Perhaps some of you may know. There is a book made by Kālidāsa, Śakuntalā. This Śakuntalā is supposed to be the most beautiful girl in the world, and she was born by this combination of Viśvāmitra Muni and Menakā.
