Sage Mode is the result of the user infusing their own chakra with Natural Energy, an energy that is given off by the environment around them. Sage Mode enhances the user's power, with the Natural Energy being described as adding a new dimension to the user's chakra. Three versions of it exist in canon, two of which are bound to the Snake and Toad summoning contracts respectively. The third is Hashirama's Wood Sage Mode.
Additionally, each version can be divided into Imperfect and Perfect variations. Imperfect Sage Mode deforms the user, the result of an imperfect balance between chakra and Natural Energy. Likewise, Perfect Sages don't experience the physical deformation, but can force an Imperfect transformation if they so choose. Perfect Sages even have enough control to instantly activate Sage Mode, albeit with a more limited pool of Sage Chakra. Speaking of the former, Imperfect Sages require at least a turn of meditation where they stay completely still to enter Sage Mode. Sage Chakra is how much of the user's chakra they've split off and molded with NE to sustain Sage Mode; the Mode ends when the user has exhausted the pool of Sage Chakra built up.
