This is a Mantra for the Green Tara. Here an explanation of the exact meaning of the words (by Kyabje Lama Thubten Zopa Rinpoche).

- Tare shows that Mother Tara liberates living beings from samsara, from true suffering, or problems. You can relate this to the particular suffering or human beings: birth, old age, sickness and death; meeting undesirable objects and experiencing aversion; not finding desirable objects or finding them but gaining no satisfaction… All these are the problems of true suffering. If you rely upon Tara by taking refuge in her and doing Tara practices-such as reciting of mantras or praises – with Tare, Tara liberates you from all these true sufferings.

– The second word, Tuttare, liberates you from the eight fears. There are eight fears related to external dangers from fire, water, air, earth and also from such things as thievesa and dangerous animals. However, the main dangers come from ignorance, attachment, anger, pride, jealousy, miserliness, doubt and wrong views. These eight disturbing thoughts that you have in your mind are the main dangers…. This second word,Tuttare, which liberates you from the eight fears, frees you from the true cause of suffering: karma and the all-arising disturbing thoughts.

– The third word Ture, liberates you from disease. Now, of the Four Noble Truths, Ture shows the cessation of suffering, which is the ultimate Dharma. In terms of liberating from disease, the actual disease we have is ignorance not knowing the absolute nature of the I, and all the disturbing thoughts that arise from this ignorance… By liberating us from disease, Ture actually liberates us from the true cause, disturbing thoughts, and also the true sufferings.

– The rough meaning for these three words Tare Tuttare Ture is: “To you, embodiment of all the Buddhas’ actions, I prostrate always – whether I am in happy or unhappy circumstances – with my body, speech and mind.”

–The final word Soha means establishing the root of the path within your heart. In other words, by taking refuge in Tara and doing Tara practice, you receive the blessings of Tara in your own heart. The gives you space to establish the root of the path, signified by Tare Tuttare Ture, in your heart. By establishing the path of the three capable beings within your heart, you purify all impurities of your body, speech and mind, and achieve Tara’s pure vajra holy body, holy speech and holy mind, which are signified by om. Your body, speech and mind are transformed into Tara’s holy body, holy speech and holy mind. This is the rough meaning of om Tare Tuttare Ture Soha.
