An accomplished, Purnayogi in the path of Kundalini Yoga is in possession of eight major Siddhis, viz., Anima, Mahima, Laghima, Garima, Prapti, Prakamya, Vasitvam and Ishitvam.
Anima: The Yogi can become as minute as he pleases.
Mahima: This is the opposite of Anima. He can become as big as he likes. He can make his body assume a very large size. He can fill up the whole universe. He can assume a Virat Svarupa.
Laghima: He can make his body as light as cotton or feather. Vayustambhanam is done through this Siddhi. In Jalastambhanam also the power is exercised to a very small degree. The body is rendered light by Plavini Pranayama. The Yogi produces a diminution of his specific gravity by swallowing large draughts of air. The Yogi travels in the sky with the help of this Siddhi. He can travel thousands of miles in a minute.
Garima: This is the opposite of Laghima. In this the Yogi acquires an increase of specific gravity. He can make the body as heavy as a mountain by swallowing draughts of air.
Prapti: The Yogi standing on the earth can touch the highest things. He can touch the sun or the moon or the sky. Through this Siddhi the Yogi attains his desired objects and supernatural powers.

He can understand unknown languages also. He can cure all diseases.

It is the process by which a Yogi makes himself invisible sometimes. By some writers it is defined to be the power of entering body of another (Parakaya Pravesh). Sri Sankara entered the body of Raja Amaruka of Benares. Tirumular in Southern India entered the body of a shepherd. Raja Vikramaditya also did this. It is also the power of keeping a youth-like appearance for any length of time. Raja Yayati had this power.
Vashitvam: This is the power of taming wild animals and bringing them under control. It is the power of mesmerising persons by the exercise of will and of making them obedient to one’s own wishes and orders. It is the restraint of passions and emotions. It is the power to bring men, women and the elements under subjection.
Ishitvam: It is the attainment of divine power. The Yogi becomes the Lord of the universe. The Yogi who has this power can restore life to the dead. Kabir, Tulsidas, Akalkot Swami and others had this power of bringing back life to the dead.

Power Of A Yogi
A Yogi forgets the body in order to concentrate the mind on the Lord. He conquers heat and cold by mastering breath-control and by controlling his nervous system.
A Yogi generates psychic heat in the body through the practice of Bhastrika Pranayama.
He can bear extremes of climates without discomfort.
He sits on the snow and melts it by the warmth generated in his body.
A Yogi covers his body with a sheet dipped in very cold water and dries it by the Yoga heat given off from his body. A few adepts have dried as many as thirty sheets in a single night.
A perfect Yogi cremates his body in the end by the Yogic heat generated by his power of Yoga.
Instructions On Siddhis
1. By the process of Hatha Yoga, the Yogi attains perfect physical body—Rupalavanya Bala Vajrasam-hanana Kaya Sampat. “The perfection of the body consists in beauty, grace, strength and adamantine hardness.” The power to bear extreme cold and heat (Titiksha), the power to live without water and food and other powers come under the category of Kaya Sampat (perfection of body).
2. Since the body of the Hatha Yogi is perfect and firm, his mind also is firm and one-pointed. By the practices of Dharana and Dhyana, he reaches the highest rung in the Yogic ladder and attains Immortality through Yogic Samadhi. The Yogi who has reached the highest stage, will have the 8 major and all the minor Siddhis.
3. Attainment of powers depends upon the amount of concentration at different Chakras and Tattvas and awakening of Kundalini. The practice of Mudras, Bandhas, Asanas and Pranayamas will also help a lot in acquiring Siddhis.
4. The Siddhis that are obtained by the practice of Mudras can be obtained by the practice of Bandhas, Asanas, Pranayamas and also by the concentration on different Chakras. That depends upon the temperament and capacity of the aspirants. One can obtain the desired goal by one exercise and others by different methods. Therefore if one is not able to get success by a particular exercise, he will have to have recourse to other exercises.
5. Many of the 8 major Siddhis are not possible at all at the present age (Kali Yuga), when the body and mind of the vast majority are not fit enough. Even today there are several Siddhas who have the power to perform some of the Siddhis. When people approach them to do this and that, they hide themselves or generally say:—“I do not know.” They are not much particular about these Siddhis. Their aim is to ignore these as unreal and aspire to reach the highest. They are the only real Yogins. Many are able to use some powers and they do not know how they are able to do them.
6. One can read the thoughts of others. A man in London hears the spiritual message of sages in India. You have seen several persons removing the poison of cobras by chanting some Mantras or by mere touch. By giving some sort of leaves, incurable diseases are cured. There are men who will very accurately tell your past, present and future. Some are able to see astral entities. Stopping the functions of the heart and changing the mind of others and other powers are due to Yogic practices.
7. Nowadays you cannot find a man who has developed all the powers. When one gets certain powers, he stops there by the influence of Maya and false Tushti (satisfaction) and uses the powers for his livelihood or for fame. Therefore he is not able to proceed further and attain perfection. It is not the mistake of the Yogic Kriyas. You should not lose faith. Faith, attention, sincerity and earnestness will lead you to success. — SRI SWAMI SIVANANDA A DIVINE LIFE SOCIETY
