He carried both the parents on his shoulders (like a water pot carrier with them put in baskets hung from a pole) and accompanied by his brothers, went in search of Dattatreya as directed by Renuka. She was in meditation and when the right spot came asked Parashurama to put them down and pointed out the cave where Dattatreya was staying and asked him to go and request Him to guide the last rites.
When Parashurama reached the cave, he found Datta sporting with some damsels and appearing very drunk. When he approached Datta and told Him the purpose of his mission, He cursed him, abused him as a mad man and asked him to get lost! He was not the man that he was looking for and was a drunkard and a womanizer and it was sheer madness on his part to ask Him to help in such matters.
After getting rebuffed a few times like that Parashurama mentioned that his mother Renuka sent him and immediately the whole demeanor of Datta changed. He gave up all pretence of being a drunkard and a womanizer and came out of the cave and paid His respects to the divine mother Renuka. He ably guided Parashurama to carry out the last rites of his parents
Once he completed the last rites of his parents, he took permission from Datta (whom he considered as his Guru) and went around the earth twenty one times and cleansed the earth of the evil kshatriya kings. He collected the blood in a kund (near kurukshetra) and offered tarpan to his ancestors. They appeared to him and suggested that he should give up the path of violence and realize his true nature. Parashurama repented and went to the forests and did great penance. He also went to his Guru and with his blessings, he realized his true nature (Brahma Gyan).

The highest truth was first taught by Lord Shiva to Lord Vishnu. Lord Vishnu incarnated on earth as Sri Dattatreya, Lord of the Avadhutas, who taught this to Parasurama, who later taught it to Haritayana.

Note
In the Shaiva sect, the three strands of the sacred thread represent the three horizontal lines of holy ash (tripundra) on the forehead of Lord Shankar which symbolize
- spiritual knowledge (dnyan),
- purity and
- penance (tapashcharya). The Brahmagath indicates the origin of these three, that is divine consciousness (chaitanya).
