Srimad Bhagavatam Canto 11, Chapter 15 - Mystical Perfection: The Siddhis
Siddhi can be translated as perfection or accomplishment. All religions accept the phenomenon of supernatural powers.
Eight main powers (Ashta Siddhis) acquired by a spiritual person as listed in the scriptures are Aṇimā, Mahima, Garima, Laghima, Prāpti, Prākāmya, Iṣiṭva, Vaśitva. There are other lists of such powers too, however these are the most discussed yogic powers.
Ashta Siddhis (supernatural powers) are:
1. Animā:
Ability to reduce the size of the body, sometimes even to the size of the atoms. ('Becoming smaller than the smallest' as described in Srimad Bhagavatam by Lord Krishna)
Example:
- Hanuman had reduced the size of his body while he was searching for Sita in Lanka.
- Hanuman had reduced the size of his body while he was searching for Sita in Lanka.
2. Mahima:
Ability to assume a gigantic form ('Becoming larger than the largest' as described in Srimad Bhagavatam by Lord Krishna)
Example:
- Hanuman assumed a huge form to burn Lanka, he also assumed big form to fight Kumbha Karna
- In Vaamana avatar Lord Vishnu increased his form which was so gigantic that it only took him three steps to cover all three worlds
3. Garima
Ability to become very heavy in weight by will
Example:
- Hanuman made his tail very heavy that even Bhima couldn't lift it (Bhima who was climbing the GandhaMadana mountains to get Saugandhika flowers for Draupadi was stopped by a monkey whose tail was on the way, Bhima orders the monkey to take the tail off the road, monkey being old tells him to move it himself, but Bhima couldn't even lift the monkey's tail)
- Hanuman made his tail very heavy that even Bhima couldn't lift it (Bhima who was climbing the GandhaMadana mountains to get Saugandhika flowers for Draupadi was stopped by a monkey whose tail was on the way, Bhima orders the monkey to take the tail off the road, monkey being old tells him to move it himself, but Bhima couldn't even lift the monkey's tail)
4. Laghima
Laghima comes from the word laghu, which means small or light. Laghima is the ability to make the body very light ('Becoming lighter than the lightest'). Levitation and flying in the air are its subsidiary powers
5. Praapti
Word praapti means 'to obtain', 'having obtained', 'to have got'. Thus praapti is the ability to acquire anything anywhere.
6. Praakaamya
The ability to obtain anything desired, ability to have realized the dreams
7. Isitva
Isa=lord; isitva=lordship; The power of absolute lordship over entire creation

The ability to have everything under control, especially the physical manifestation made up of five elements
