Knowledge is power.
Keep your Face to the SunShine
Reality of the life is quite different. What we think to do, not necessarily we can do it. If everybody can do everything then nobody will be poor and everybody will be successful. However, some people have 'no Impossible' term in their dictionary and these people, most probably, succeed in their lives.
Positive thinking always keeps us ahead of others, determination to face every challenge is the essence of struggle, hindrances co e on the way but they remove all these hindrances and achieve their target.
Another incident from the same epic Ramayana is bringing Sanjeevani to cure Lakshmana. Again same Hanuman did the miracle with his power and saved Lakshmana.
Definitely, if we have a desire we will rise to the occasion and see that we will perform well and make impossible works possible.
